I got into data science through nursing, I was an ICU nurse looking for a hiatus in the job, that’s how I broke into the field, via the hospital system but I do have a secondary degree in bio chemistry which helped significantly on the quantitative side of things. Bio statistics is a staple in an biochemistry program and if anyone else’s prof’s were like mine, you’d swear they were teaching engineering in the amount of quantitative topics I was put through. I was however very weak on the he business end of things and had to be paired with someone for about a solid 8 months. But it was an awesome transition to another career.

That's very important when you have along video you have to have an index so the people don't get bored, that should include the time in each subtitle, a thing that you have to correct.
I came from a business school, fell in love with statistics, and decided to become a teaching assistant there... Little did I know back then that it's the reason why I'm in this data science rabbit hole. And I'm loving it so far!!!! Edit: Just discovered I'm on the rare category. 🤯
I have gone through the whole video and am really grateful for the time you've invested in this. The vivid pictures and friendly speaking pace were truly refreshing and helped balance the ubiquity of the text. Cheers from Abidjan!
I am only 2 hours in but I LOVE the way you demystify what I once thought was so out of my league/ability and perhaps interest as well. Thank you so much!!!
Hey cassandra, was this helpful for beginners? I want to start, and i needed to know whether this is where u started or there is another video i may watch to begin before this
Omg! I’m a psychologist that is interested in Data Science too. I thought that I was the only one. Even I’m learning English, in exhausting form, because there’s lack of information in Spanish. Thanks for the content and all your job in the channel!
This guy is motivating and teaching you data science in under 6 hours that no one could teach you. 10-12 ads are totally fair, others hire paid teachers and still can't understand a thing. This guy is making many's life. Watching this video before starting and between your data science career, you can be the data scientist that everyone wants. Thank you, Barton Poulson and Freecodechamp for this life-changing course.
Hey 👋.....Can an Msc Biotechnology Graduate learn data science and get certified and can they be hired by companies to become data scientist? Or only computer science background students can get this job??
@@Dariusrae45636You can be a data scientist if you don't even have a strong background from computer science. Even many people who are data scientist now are mostly from other fields, sometook enginnering fields and some took other.
I'm not gonna lie, there is no chance I'm going to watch all of this, but from what I've seen so far, this is an AMAZING beginners guide to understand every facet of data science. Thanks for this awesome resource. I'm excited to see more resources popping up showcasing more projects and real world experience beginners can learn from
Half way in and this looks more like an overview than a training. Not sure you will learn data science by watching this but you will get the picture of what’s involved.
please try to upload some basic projects of how data scientist do their work professionally in the industry it will literally help students to learn in real time.
A fully-worked example project would be wonderful. Is there a particular kind of project that would be most useful to you? And is there a language that would be best?
@@datalabcc all the jobs that are link to data uses python quite vast so working and practicing every attribute of this language helpful and beneficial for all the novice students for instance we know how to manipulate basic data set with some python commands but we dont know all the working stages of data scientist or data analyst in the real time industry and how a project is to be done and what possible outcomes does the industry make after when a data scientist completed their job on a given data set and what makes them worth to earn thousands of money believe me this gonna work like a big motivation for the students.all in all let me give an example take basic data set like uci-iris and do all the necessary work on it upto maximum extent and what possible results comes out from this especially what we looking in it and why and how to make final report of any particular data set after completing it and what decision could be made when the company manager sees it.
Hello! I just finished the whole video and would like to say thanks! I hope this starts out my journey in learning more about data science. This provided a wide overview of the concepts, tools, and thinking that will be needed in DS. Without being daunting and yet not mind-numbingly dumbed down. Again, thank you!
This Course is made more towards for what the real and practical advice for work that needs to be done in one video, not for actual learning of ML, DL, LLM, CV or really anything specific as a skill not exactly what I was Looking for.
As a student of political science and international affairs with some background in anthropology and sociology, I was abnormally interested in this area, specially explained in such beautiful manner, but when you added the social sphere everything clicked, and hence why they are considering me for an internship. This would be fun if with a proper team.
finished the full 6 hour course. very imformative . i was thinking of learning R for my research analysis. before that i thought i need some foundation on data science and i saw this video. thanks a lote❤
This is a great video! Very well explained concepts. As an established data scientist myself, it helps to have resources like these to brush up on my fundamentals. I also have a few videos on my channel that talk more about the experience working as a data scientist for those that are interested!
A hearty thanks, ❤ I just completed my 10th boards, And was in search of a best career option for self with all the clarifications , And you this video, made me get it perfectly with no doubt remained in me , And really the ones who are contributed in makeing this video are psychologists, who actually knows how we (students) do think ! Really meant alot ❤❤❤
I did it , and survive So generous to have made this, Thank you ! the Plus , excellent narrative, but i would suggest to take a real life DATA science project and stick one by one the concepts you have patiently teach for 6 hours . if not the concept are TOO ABSTRACT to be RETAIN. OVERALL , Great but adding a real DATA science project from A to Z would be AWESOME ! Thanks
A fully-worked example project would be wonderful. Is there a particular kind of project that would be most useful to you? And is there a language that would be best?
This is excellent even for people already working in related fields because it talks about many tools and concepts they may have overlooked. The organization, clarity, and Paulson's breadth of knowledge are impressive!
@@datalabcc Thanks for this incredible lecture. I was wondering if you could also let me know where I can get the data sheet (excel) from. I did download a few samples from Kaggle as you suggested, but was hoping to work on your datasheet first and then on the rest. Most of the ones on kaggle do not have a defined datatype in the rows. So it's being a bit tricky there especially the ranged columns.

I know this is a late comment, and I'm not sure how far along in your learning. That being said, my answer to you is this: fortunately, the programming fundamentals between Data Science and Software Engineering are interchangeable. However, it depends on how you want to use those programming languages. If you prefer building infrastructure and pipelines, full-stack websites, and data environments, software engineering is more for you. In contrast, if you enjoy cleaning and dissecting data, and optimizing company workflow with information being processed across several statistical measures, data science is more for you. Both are algorithm and math heavy, the deeper you go. From what I've seen/read (as I'm not someone there yet) at the higher levels, data scientists and data engineers choose which they want to prioritize. Both fields are highly attractive, highly sought, and highly necessary.
Quincy if u are reading this......We all campers really appreciate from bottom of our heart for whatever u r doing for us. I just want to say that nobody gives a damn if u start putting ads in between the videos. I have an ad blocker but for the sake of this channel I'll disable it, as that's the only way I can contribute right now and there are many more like me. Start putting ads.
Best video ever for 360 degree understanding of the field of data science!! I’ve only watched 20-odd minutes, but already I have so much clarity. Plan to do the entire series. Thank you!
Thank you ❤. I'm not a techy person. However the way you handle the material is so smooth, so compelling that my fears have disappeared and I'm ready to start learning
Great course! Content is informative, well structured, and explained clearly. It is evident that Barton Poulson is very knowledgeable and his personality really shows through. His spirit is encouraging and I thoroughly enjoyed his humour. Keep up the inspiring work!
Amazing course! I'm having a turn in my career after 10 years of school teaching, and this course is just what I needed to complement my studies in DS. Just an _errata_ : at 2:13:20 you mentioned "data de novo" as your personal expression for the concept of "new data". I don't know you if it meant for this expression to be extracted from portuguese language or latin, but if you took it from portuguese, the adequate expression should be "Nova Data" or "Novo Dado". In portuguese "de novo" means the same as "again" or to do something one more time.
Sir, you are one of the best lecturers whose class I've had the good fortune of stumbling across. Your philosophical backdrops and psychological insights made the experience ever so more pleasant and freshly original.
Over so many instructors, the speed and clarity of this instruction is the best. Some of the professors that teach course over MOOC, they were chasing for the next train. TQ FCC...
Please keep in mind that this course was originally published in 2016. It seems like it's a wonderful take on the foundations of Data Science, but some of the information may be missing and/or outdated.
A must watch video for anyone who is interested in Data Science. * Excel is highly used in reality, VBA based on Excel should be considered as a programming language
This is Bart Poulson, who created the video. I spend a truly inordinate amount of time telling all of the data science people I work with that they need to be fluent in spreadsheets, first and foremost. VBA is absolutely a programming language and I apologize if I suggested otherwise. It's a fabulous tool!
I spent over 10 years in marketing (Web analytics, A/B testing, Conversion Rate Optimization, online ads etc. - so basically I always was on this technical/business side of marketing) and 1.5 years with Python (web scrapping, automation) but I always sucked at math. Big time. Data Science and ML are extremely interesting for me, I can see many applications for my day-to-day work in marketing but I'm scared shitless of this math part :)
Michael, this is Bart Poulson, who created this course. It sounds to me like you already have most of what you need and, unless you're going into algorithm development, huge amounts of math may not be necessary. I imagine that your familiarity with analytics and experience with automation already does a lot for you. But what specific plans do you have?
I’m a financial analyst right now but I already know SQL and Power BI. I’d like to learn Python and R so I can move to a role where I can combine my existing finance knowledge with data science
Hai sir ....your work in this data science field ......if you know can you explain please.... I am willing to start my new career's in data science field
Love your voice I could hear for the next 6 hours without any distraction... lot of misunderstandings N abilities many more were covered with ease... completed in two days the course... As you said that u were from psychology did very well in implementing things on very one cud be part of data science.. so much encouragement... Love your work N following you... All the best for your future N i update my Data science enhancement from being a beginner..
Hi, In Part 3, Coding, Prof Poulson refers to downloading spreadsheets and other downloadable data to test with tableau, please can you give me the url so I can download them?
i know you dont want to interfere your students with ads when they are watching videos but dude there is a options in monetization section where you can specify which ads you want to show on your videos leki you can enable sideview ads (ads above the video recommendations). I love that you are providing all of this stuff without earning a penny. I really want to give you some economic boost but i seriously dont have money. enable that ads to make more money to produce more quality content like this Thanks again!!
Thank you so much for your detailed course it really helped me in getting motivated in starting to become a data scientist for the first time in my life I am confident about pursuing something! My journey will start from today wish me luck
Thank you all for an amazing video. Could you please upload a video how we can implement data science on real life data. Like using python or R programming with SQL and these concepts. thanks again.
Thanks to every single person who contributed their time to make this video.
Agreed!

Thanks man
This has to be one of the best videos Ive ever seen. Ever. It was like listening to an interactive audio book. Thank you so much
2:12:19 so far and cannot imagine how much effort these guys have put to make this. This is really a beautiful attempt. This is great. Thank you, FCC.

Edit: Just discovered I'm on the rare category. 🤯
I have gone through the whole video and am really grateful for the time you've invested in this. The vivid pictures and friendly speaking pace were truly refreshing and helped balance the ubiquity of the text. Cheers from Abidjan!
Barely 10 minutes in and can already appreciate the time and consideration put into this video. Thanks so much.
Wow am so 😀 glad
Bro gave up 4 years ago lamo
I am only 2 hours in but I LOVE the way you demystify what I once thought was so out of my league/ability and perhaps interest as well. Thank you so much!!!
Hey cassandra, was this helpful for beginners? I want to start, and i needed to know whether this is where u started or there is another video i may watch to begin before this

There is nothing out of your league , hope things are going well for you ...
One the most calming voice and tone I've heard. I need this guy in my life for daily calm ! :-))

1:05:41 so far it's the best and most clearly explained video on data science I've watched so far. Awesome job.
may i ask u ..because im also confused ..which video to watch .. like ..data science from Edureka,simplilearn,intellipat
How can you watch this and *not* leave a thumbs up? Brilliant, even for practicing ML engineers!
I got through everything and I have to say: thank you very sooo much for all the value you supplied us for free!!! This is just amazing
Omg! I’m a psychologist that is interested in Data Science too. I thought that I was the only one. Even I’m learning English, in exhausting form, because there’s lack of information in Spanish.
Thanks for the content and all your job in the channel!
Ok sidenote, this guy has the most calming voice ever. Like he could talk about literally anything and I'd listen to it
You can say that again!!!
Just finished this 6 hours videos. Thank you for your kind sharing.
Really easy to understand and very useful.
This guy is motivating and teaching you data science in under 6 hours that no one could teach you. 10-12 ads are totally fair, others hire paid teachers and still can't understand a thing. This guy is making many's life. Watching this video before starting and between your data science career, you can be the data scientist that everyone wants. Thank you, Barton Poulson and Freecodechamp for this life-changing course.
Hey 👋.....Can an Msc Biotechnology Graduate learn data science and get certified and can they be hired by companies to become data scientist? Or only computer science background students can get this job??
@@Dariusrae45636You can be a data scientist if you don't even have a strong background from computer science. Even many people who are data scientist now are mostly from other fields, sometook enginnering fields and some took other.
@@epicsizzly thank you so much

This video was perfect. I am speechless. Thank you so much. The narrator is brilliant.
I'm not gonna lie, there is no chance I'm going to watch all of this, but from what I've seen so far, this is an AMAZING beginners guide to understand every facet of data science. Thanks for this awesome resource. I'm excited to see more resources popping up showcasing more projects and real world experience beginners can learn from
Great course we need its updated version ! Who is with me smash like button
Half way in and this looks more like an overview than a training. Not sure you will learn data science by watching this but you will get the picture of what’s involved.
please try to upload some basic projects of how data scientist do their work professionally in the industry it will literally help students to learn in real time.
Yes please. That'll be very useful
A fully-worked example project would be wonderful. Is there a particular kind of project that would be most useful to you? And is there a language that would be best?
@@datalabcc all the jobs that are link to data uses python quite vast so working and practicing every attribute of this language helpful and beneficial for all the novice students for instance we know how to manipulate basic data set with some python commands but we dont know all the working stages of data scientist or data analyst in the real time industry and how a project is to be done and what possible outcomes does the industry make after when a data scientist completed their job on a given data set and what makes them worth to earn thousands of money believe me this gonna work like a big motivation for the students.all in all let me give an example take basic data set like uci-iris and do all the necessary work on it upto maximum extent and what possible results comes out from this especially what we looking in it and why and how to make final report of any particular data set after completing it and what decision could be made when the company manager sees it.
Yes That will be very helpful
The best tutorial on Data Sci Intro..hands down! He is a psychologist - he knows how to engage a student. Kudos!
Hello! I just finished the whole video and would like to say thanks! I hope this starts out my journey in learning more about data science. This provided a wide overview of the concepts, tools, and thinking that will be needed in DS. Without being daunting and yet not mind-numbingly dumbed down. Again, thank you!
How is it
How has your learning been thus far?
How is it going??
i am in a DS bootcamp working on a project. Still not good coding but I am enjoying the "creative" and free process of resolving problems.

This is an absolutely great intro to data science. Sadly most job posts seem to want you to also be a full cycle software developer.
They going to start retiring soon and the crumbling will be crazy
Add prompt engineer title as well with AI
This Course is made more towards for what the real and practical advice for work that needs to be done in one video, not for actual learning of ML, DL, LLM, CV or really anything specific as a skill not exactly what I was Looking for.
One of the best introductions ever in data science and big data! Great job!
Terima kasih diatas penjelasan anda.
Agak rumit juga perkembangan ilmuan kini.
As a student of political science and international affairs with some background in anthropology and sociology, I was abnormally interested in this area, specially explained in such beautiful manner, but when you added the social sphere everything clicked, and hence why they are considering me for an internship. This would be fun if with a proper team.
finished the full 6 hour course. very imformative . i was thinking of learning R for my research analysis. before that i thought i need some foundation on data science and i saw this video. thanks a lote❤
This is a great video! Very well explained concepts. As an established data scientist myself, it helps to have resources like these to brush up on my fundamentals. I also have a few videos on my channel that talk more about the experience working as a data scientist for those that are interested!
A link to your channel please

I just completed my 10th boards,
And was in search of a best career option for self with all the clarifications ,
And you this video, made me get it perfectly with no doubt remained in me ,
And really the ones who are contributed in makeing this video are psychologists, who actually knows how we (students) do think !
Really meant alot ❤❤❤
I did it , and survive So generous to have made this, Thank you ! the Plus , excellent narrative, but i would suggest to take a real life DATA science project and stick one by one the concepts you have patiently teach for 6 hours . if not the concept are TOO ABSTRACT to be RETAIN. OVERALL , Great but adding a real DATA science project from A to Z would be AWESOME ! Thanks
A fully-worked example project would be wonderful. Is there a particular kind of project that would be most useful to you? And is there a language that would be best?
OMG JASP and OSF is amazing!!! Thank you Bart!!!
This is excellent even for people already working in related fields because it talks about many tools and concepts they may have overlooked. The organization, clarity, and Paulson's breadth of knowledge are impressive!

This is Barton Poulson, who created the video. Thanks so much for the kind words; I'm glad it was helpful!
@@datalabcc Thanks for this incredible lecture. I was wondering if you could also let me know where I can get the data sheet (excel) from. I did download a few samples from Kaggle as you suggested, but was hoping to work on your datasheet first and then on the rest. Most of the ones on kaggle do not have a defined datatype in the rows. So it's being a bit tricky there especially the ranged columns.
...got a job from this? No? Who cares.

34:45 -" Data Science is not equal to Coding." Can I practice both at the same time. Can I be the master of both at same time.
I know this is a late comment, and I'm not sure how far along in your learning. That being said, my answer to you is this: fortunately, the programming fundamentals between Data Science and Software Engineering are interchangeable. However, it depends on how you want to use those programming languages.
If you prefer building infrastructure and pipelines, full-stack websites, and data environments, software engineering is more for you. In contrast, if you enjoy cleaning and dissecting data, and optimizing company workflow with information being processed across several statistical measures, data science is more for you.
Both are algorithm and math heavy, the deeper you go. From what I've seen/read (as I'm not someone there yet) at the higher levels, data scientists and data engineers choose which they want to prioritize. Both fields are highly attractive, highly sought, and highly necessary.
The best data science class I have seen in UA-cam
I'm so glad to hear it!
Quincy if u are reading this......We all campers really appreciate from bottom of our heart for whatever u r doing for us. I just want to say that nobody gives a damn if u start putting ads in between the videos. I have an ad blocker but for the sake of this channel I'll disable it, as that's the only way I can contribute right now and there are many more like me. Start putting ads.
Hello from Brazil!! I just would like to say THANK YOU so much!! This video help me in many quests that a had about this area! Thank you! :)
Starting my journey towards DS. its my first lecture. Thanks for this … i also need volunteer mentor to guide me.
Best video ever for 360 degree understanding of the field of data science!! I’ve only watched 20-odd minutes, but already I have so much clarity. Plan to do the entire series. Thank you!
Thank you ❤. I'm not a techy person. However the way you handle the material is so smooth, so compelling that my fears have disappeared and I'm ready to start learning
Great course! Content is informative, well structured, and explained clearly. It is evident that Barton Poulson is very knowledgeable and his personality really shows through. His spirit is encouraging and I thoroughly enjoyed his humour. Keep up the inspiring work!
Bro is this beginner Friendly and full course ?
Amazing course! I'm having a turn in my career after 10 years of school teaching, and this course is just what I needed to complement my studies in DS. Just an _errata_ : at 2:13:20 you mentioned "data de novo" as your personal expression for the concept of "new data". I don't know you if it meant for this expression to be extracted from portuguese language or latin, but if you took it from portuguese, the adequate expression should be "Nova Data" or "Novo Dado". In portuguese "de novo" means the same as "again" or to do something one more time.
Sir, you are one of the best lecturers whose class I've had the good fortune of stumbling across. Your philosophical backdrops and psychological insights made the experience ever so more pleasant and freshly original.
This is Barton Poulson, who created the video. I'm so glad you enjoyed the course! Thanks for the wonderful feedback.
Over so many instructors, the speed and clarity of this instruction is the best. Some of the professors that teach course over MOOC, they were chasing for the next train. TQ FCC...

@@rafaykhan9579 Thanks Rafay!!! Means alot :)
Please keep in mind that this course was originally published in 2016. It seems like it's a wonderful take on the foundations of Data Science, but some of the information may be missing and/or outdated.
A must watch video for anyone who is interested in Data Science.
* Excel is highly used in reality, VBA based on Excel should be considered as a programming language
This is Bart Poulson, who created the video. I spend a truly inordinate amount of time telling all of the data science people I work with that they need to be fluent in spreadsheets, first and foremost. VBA is absolutely a programming language and I apologize if I suggested otherwise. It's a fabulous tool!
I spent over 10 years in marketing (Web analytics, A/B testing, Conversion Rate Optimization, online ads etc. - so basically I always was on this technical/business side of marketing) and 1.5 years with Python (web scrapping, automation) but I always sucked at math. Big time. Data Science and ML are extremely interesting for me, I can see many applications for my day-to-day work in marketing but I'm scared shitless of this math part :)
Michael, this is Bart Poulson, who created this course. It sounds to me like you already have most of what you need and, unless you're going into algorithm development, huge amounts of math may not be necessary. I imagine that your familiarity with analytics and experience with automation already does a lot for you. But what specific plans do you have?
I like how much material is looked over before even coding is even introduced, a good insight into the applications of data science.
I have 101 udemy courses in my account that is half completed lol . I will complete almost all within this year . staying motivated is hard

i know you dont want to interfere your students with ads when they are watching videos
but dude there is a options in monetization section where you can specify which ads you want to show on your videos leki you can enable sideview ads (ads above the video recommendations).
I love that you are providing all of this stuff without earning a penny. I really want to give you some economic boost but i seriously dont have money.
enable that ads to make more money to produce more quality content like this
