Word: Data Scientist Description: Data Scientist are people who uses data to create impact for the organization through insights, product recommendation and etc. Where to find a Data Scientist: You will often see data scientist in public places like bridges, if there are too many people in the bridge, look for the person dancing goofily.

I wish I saw this 6 months ago! I've been trying to transition careers from physics to "data science" and after not having much luck despite what I thought to be very similar methods used in my former career, now its becoming clear why my resume is getting nowhere... I've focused on the top too much, haven't showcased my whole pyramid. Thank you bro!
Hey Cadmus! Great to hear you’re trying to transition 😊 Fellow data scientist and small UA-camr here, I’ve got a lot of videos up on my channel that talks about how to break into the industry and my advice, maybe it could help you out? :)
Could you do a video showing some actual day to day activities on the job. Basically putting some of the things videos mentioned into context with some real life examples would be great (I understand this may be tough because of company rules on privacy/security etc) but anything of the sort is appreciated!
Completely agree, as a data scientist in telco company most of time what i needed i just SQL to retrieve data, Tableau to make quick insight, Python with Jupyter Notebook to build model and experiment with dataset after assessing from data insight and business knowledge.
Can you explain what you mean with the Python part? My working experience is similar to yours; It starts at retrieving data with SQL but ends in Power BI for analysis. What does Tableau for example lack in comparison to Python?
@@BeunckensJeroen I am interested in it as well, I am a beginner in DS just freshly graduated. I don't understand why python is needed when tableu can pretty much generate visualizations given the data is clean and all.
@@hmZ93094 I don't know how tableau works but if I am not mistaken it is a software built for data visualisation, which means it is not as flexible as using Python where you can do whatever you want if you control the language and packages such as matplotlib

Consistent nomenclature would be amazing, but startups are such havoc on that notion! Thanks for breaking down the startup vs midsize vs deep pocket lingo. It's easier to guess the actual role scope by company size and industry with a good breakdown like this.
It's a breath of fresh having someone so simply express the breadth of this career field. An onslaught of technical terms do little but confuse the curious. I will now quote mine Einstein: “If you can't explain it to a six year old, you don't understand it yourself.” Good video friend!

thank you! recently, i saw in my career path that I will have to choose between data scientist, data engineering, automation or development (traditional). well, in some videos some people say that data engineers will "connect" better with CEO's (or will by better paid), but, the things you can learn choosing data scientist are more "technical" in a way. they'll teach you mathematics, inference and integrals while in data engineering not. Saludos desde Chile!
Thanks a lot for explaining the terminology associated with DS jobs at various levels of the hierarchy 👏 👍 Makes it much easier now to apply to the _right_ job titles, rather than accidentally to a similar-sounding job that one actually *doesn't* wanna apply for 🙂
The entire data science scene on UA-cam is one of the most convoluted I have ever come across. You guys use the most complicated programs and lingo and each one of you tells a different story about what data science is.
Thank you so much for your videos. Ever since I was a kid I wanted to be a computer scientist but while growing uo I discovered there are actually different branches to it. But you breaking this down gives me more knowledge of what I should branch into and learn more. I am in my third year in college and I am not going to lie it has been tough but I know it will get better with time. I have watched about 5 different videos just tonight that I found this channel, lol. Thanks again, Mr. Joma.
Thanks Joma! After watching this video I regain my confidence to work in the industry. All other video mostly just either discouraging for very technicals or simply misleading, was feeling kinda dumb when I'm no expert in Deep Learning and want to work in the industry as a DA, Analytics. Thanks for clearing the clouds, mate! :D
Thank you so much for the insightful explanation. I would like to see what kind of portfolio we might need to prepare to start looking for a job as a Data Analyst. I'm very new to this, so this question might be quite naïve! Thank you once again :)
My recommendation is to provide more information and tutorials starting from the bottom of the pyramid and working your way towards the top of the pyramid. This is the best recommendation for those of us who would be a one man operation working toward becoming a multiple people organization. Thanks!

Oh, and thanks, @joma !! Your vids have been super helpful fo understanding the industry landscape of DS, since I’m a new Graduate 🙏🏽 very much appreciated.
they're two completely different processes. A/B testing is about finding statistically significant differences in versions of products/services while minimizing the time/sample size needed to do so. Training and testing (and validation) are used to ensure your predictive models are not overfit--that they can generalize well to new, unseen data. But I suppose the concepts do intersect when you consider long-term use of predictive models--I have heard of companies that conduct A/B testing of different predictive models to judge when to replace old models with newer ones, given that over time the current data will begin to differ from the data used to initially train the model.
You might want to check the "A / B Testing: The Most Powerful Way to Turn Clicks Into Customers" book by Dan Siroker and Pete Koomen; the cofounders of Optimizely which is the leading company in A/B testing space: www.aioptify.com/best-ab-testing-books.php
I am a data scientist intern for an insurance company, primarily focus on the Analytics side. This is exactly I thought how Data Science is, and we should be clear there are some absolute differences between a data scientist, a data analyst, and a data engineer. Do your research and find out which area is in your interest.
You hit the nail right on the head buddy. I say this from an academic's perspective. When I look at data science for my faculty, I advocate designing and teaching subjects that engage students to think about real business problems and make recommendations backed up by data, information and presented well via visualisation techniques. However, you will be surprised how many University faculties are creating "Data Analytics" subjects that are really just rebadged finance, econometrics, programming or statistics units. They insert all the financial models, equations and calculations but have little to no analysis or analytics let alone any decision making.
Thanks for giving the comprehensive outlook what data scientists can be. It was very much confusing before watching this video but now its sorted out. Thanks a lot!
Thank you for this. I am thinking of going back to school to become a Data Scientist, and this video helped me a lot to understand what a DS' job entails.
I watched this video about 2 years ago, back than I didn’t understand anything about data science but knew clearly I want to learn more about this field. Watching this video back than was helpful but knowing what I know today (building some projects in ML during bootcamps and studying DS degree in college) made it absolutely clear now. I agree with the way you presented it and I like how you did it. It gave me better insights about a role I want to look for. Thank you for your valuable video.
Great video, very helpful how you explain the hierarchy and how it scales to different company sizes. I think it would be a great idea if you can go more into the details in how this hierarchy can be applied to other industries. I work in aerospace manufacturing and would be cool to learn data science could be implemented. Cheers!
Two questions: 1. for beginner stage, what classes do you recommend to take in college? 2. Where do Data Translators fall in this pyramid? Thank you for the video... Very helpful.
Yes, please. I also want to know how to become a Data scientist with my Master's in Manufacturing Engineering ? Can i become a data scientist.? If yes, please suggest us online platforms that are helpful to get the knowledge and complete course.
@@madhanidevang3298 There's no such formula. With a Master degree I'm sure at this point you already know it's our job to educate ourselves. TL:DR: YES! YOU CAN but you have to find your way.
As a fellow data user, it seems to me that as I work more and more in data science and as a developer - we end up wearing many, many hats. Maybe especially so when you've skilled stacked for a few years. From reviewing, validating, and updating engineering initiatives, to managing a server, to answering ad hoc questions that just require research and a quick number crunch. I've gone from trying to understand massive SQL servers, to Tableau dashboards and cloud storage management, to being asked to prep a new pipeline of GA360 data into AWS. It's fun and stressful.
This is the information I was looking for!!! Thank you very much for creating this video and sharing your valuable knowledge.I profoundly appreciate it.

Been statistics student, I fancy myself to be a Data Analyst. It's been months looking for my first entry level DA roles. But most of them need 3-5 years of experience plus tones of software skills even for junior DA. I start doubting myself. And decide to have other than DA roles jobs meanwhile up skilling myself. I still want to believe that I can make it to my dream jobs. ☺️ Thank you for this video.
Great video! I'm pretty happy that what you said is really close to my guesstimates from several experiences in small and larger companies. Another broader definition I read somewhere is about the timing of the data-related tasks, it goes: "Data Analysts look at the present and past (with Analytics), while Data Scientist look at the future (with AI & predictions)", or something like that.

Thank you so so so much for this information and clearing away so many doubts. Everyone keeps telling what Data Science is, but no one really told what it actually is and the breakdown. This makes things so much clear. Cheers!!!
Thanks for making this grand search for a major interesting and fun throughout your video! Keep it up man
Hi Joma,
Please make a series about the whole data science process using real open source data, explain every step in the pyramid while doing live coding.
Explain the tasks and the tools used in real life.
I think you might get millions of views for that, because it might be the first series of it's kind in UA-cam.
Thats 20k $ thanks
thank you! recently, i saw in my career path that I will have to choose between data scientist, data engineering, automation or development (traditional). well, in some videos some people say that data engineers will "connect" better with CEO's (or will by better paid), but, the things you can learn choosing data scientist are more "technical" in a way. they'll teach you mathematics, inference and integrals while in data engineering not. Saludos desde Chile!
this totally clarifies all of my doubts about DS, thanks
Thanks a lot for explaining the terminology associated with DS jobs at various levels of the hierarchy 👏 👍
Makes it much easier now to apply to the _right_ job titles, rather than accidentally to a similar-sounding job that one actually *doesn't* wanna apply for 🙂
This is a very informative video. And I totally agree with the perspectives you shared Joma
Hello, my name is Yang Qiao from Hong Kong, China, I hope to become friends with you, if you like, you can add my WhatsApp +852 66163679
The entire data science scene on UA-cam is one of the most convoluted I have ever come across. You guys use the most complicated programs and lingo and each one of you tells a different story about what data science is.
hey Joma!
Just want pop in and comment, this video is giving me a better understand about this job's responsibilities. Thanks Joma! :))
Thank you so much for your videos. Ever since I was a kid I wanted to be a computer scientist but while growing uo I discovered there are actually different branches to it. But you breaking this down gives me more knowledge of what I should branch into and learn more. I am in my third year in college and I am not going to lie it has been tough but I know it will get better with time. I have watched about 5 different videos just tonight that I found this channel, lol.
Thanks again, Mr. Joma.
Thanks Joma! After watching this video I regain my confidence to work in the industry. All other video mostly just either discouraging for very technicals or simply misleading, was feeling kinda dumb when I'm no expert in Deep Learning and want to work in the industry as a DA, Analytics. Thanks for clearing the clouds, mate! :D
Thank you for simplifying it all, I am currently doing what you are describing.
Thank you so much for the insightful explanation. I would like to see what kind of portfolio we might need to prepare to start looking for a job as a Data Analyst. I'm very new to this, so this question might be quite naïve!
Thank you once again :)
This is the most informative video I’ve seen on UA-cam. Thank you
My recommendation is to provide more information and tutorials starting from the bottom of the pyramid and working your way towards the top of the pyramid. This is the best recommendation for those of us who would be a one man operation working toward becoming a multiple people organization. Thanks!
"Thanks for driving...." "Shut the f*ck up"
I am subscribing because of that statement.
Me too.
Then I realized she was serious!
yeah that dude is a pushover and she was lucky he just needed a ride, couldn't be me lmao
@@onehungryboy9438 lol thats all fake dude lmao
what is her @ tho??
As a person considering a potential career shift into DS-- this is the most inciteful video i have come across. nice work!
Would love to see videos about machine learning/data science core 🤖

@Michel Tamgho thanks..just did
1:11 this is when you graduate from university of waterloo THIS THING HAD ME DYING.
Made a lot of sense after going through all those data science stuff online. You actually explain plain and simple for a decision to make upon it. Great ❤
Would like to learn more about A/B Testing! Thanks :)
Ajay Vasisht +1 how is the process different from test/train? Is it just that A/B is done live?
Oh, and thanks, @joma !! Your vids have been super helpful fo understanding the industry landscape of DS, since I’m a new Graduate 🙏🏽 very much appreciated.
www.udacity.com/course/ab-testing--ud257 that might help!
they're two completely different processes. A/B testing is about finding statistically significant differences in versions of products/services while minimizing the time/sample size needed to do so. Training and testing (and validation) are used to ensure your predictive models are not overfit--that they can generalize well to new, unseen data. But I suppose the concepts do intersect when you consider long-term use of predictive models--I have heard of companies that conduct A/B testing of different predictive models to judge when to replace old models with newer ones, given that over time the current data will begin to differ from the data used to initially train the model.
You might want to check the "A / B Testing: The Most Powerful Way to Turn Clicks Into Customers" book by Dan Siroker and Pete Koomen; the cofounders of Optimizely which is the leading company in A/B testing space:

I am a data scientist intern for an insurance company, primarily focus on the Analytics side. This is exactly I thought how Data Science is, and we should be clear there are some absolute differences between a data scientist, a data analyst, and a data engineer. Do your research and find out which area is in your interest.
Can I be a data scientist with out a CS or college degree?
@@mashooraraf344 yes you can but having a cs degree really helps. There are a lot of math and statistics majors who work as data scientist as well.
Hello
Can do data science without doing matrix?
So helpful ! And non-superfluous. I like your low key approach. Thank you :)
- Thanks for driving me.
- STFU!
Lol you'll let yourself be spoken to like the because she's hot lol ..... Shame shame on you 😉
Your budget film making skills are on point.
1:36 William S. Cleveland wanted to bring data mining to NUTTER level!
You hit the nail right on the head buddy.
I say this from an academic's perspective. When I look at data science for my faculty, I advocate designing and teaching subjects that engage students to think about real business problems and make recommendations backed up by data, information and presented well via visualisation techniques.
However, you will be surprised how many University faculties are creating "Data Analytics" subjects that are really just rebadged finance, econometrics, programming or statistics units. They insert all the financial models, equations and calculations but have little to no analysis or analytics let alone any decision making.
Would love to see a video on the "Analytics" aspect of Data Science
I would like to learn more on A/B testing and analytics. Great videos educational and entertaining.
Thanks for giving the comprehensive outlook what data scientists can be. It was very much confusing before watching this video but now its sorted out.
Thanks a lot!
Thank you for this. I am thinking of going back to school to become a Data Scientist, and this video helped me a lot to understand what a DS' job entails.
Great editing/content. I would like to know more about how to ask right questions what you do on work
I watched this video about 2 years ago, back than I didn’t understand anything about data science but knew clearly I want to learn more about this field. Watching this video back than was helpful but knowing what I know today (building some projects in ML during bootcamps and studying DS degree in college) made it absolutely clear now. I agree with the way you presented it and I like how you did it. It gave me better insights about a role I want to look for. Thank you for your valuable video.
Great video, very helpful how you explain the hierarchy and how it scales to different company sizes. I think it would be a great idea if you can go more into the details in how this hierarchy can be applied to other industries. I work in aerospace manufacturing and would be cool to learn data science could be implemented. Cheers!
Oh man, you help me begin learn what i literally need to know
Great video. Thks for sharing!
Two questions: 1. for beginner stage, what classes do you recommend to take in college? 2. Where do Data Translators fall in this pyramid?
Thank you for the video... Very helpful.
Did you find out what classes to take? Kinda in the same boat now lol
Make a video on Step by Step guide on how to be a Data Scientist / ML Engineering
Yeah, we need it.
Yes, please. I also want to know how to become a Data scientist with my Master's in Manufacturing Engineering ? Can i become a data scientist.? If yes, please suggest us online platforms that are helpful to get the knowledge and complete course.
@@madhanidevang3298 There's no such formula. With a Master degree I'm sure at this point you already know it's our job to educate ourselves.
TL:DR: YES! YOU CAN but you have to find your way.
Yes please
As a fellow data user, it seems to me that as I work more and more in data science and as a developer - we end up wearing many, many hats. Maybe especially so when you've skilled stacked for a few years. From reviewing, validating, and updating engineering initiatives, to managing a server, to answering ad hoc questions that just require research and a quick number crunch.
I've gone from trying to understand massive SQL servers, to Tableau dashboards and cloud storage management, to being asked to prep a new pipeline of GA360 data into AWS.
It's fun and stressful.
thanks man this really helped me in choosing my college courses
This is the information I was looking for!!! Thank you very much for creating this video and sharing your valuable knowledge.I profoundly appreciate it.
Thank you sooo much, I hope all the youtubers can explain thing as clearly as you can
DS is different everywhere. At Google they build models, at Facebook they are data driven PMs.
That's a bit of a sweeping generalization...
i think there are some analytic, data science job in Google too just like in facebook: careers.google.com/jobs#!t=jo&jid=/google/product-analyst-data-science-google-building-41-1600-amphitheatre-2527730235&
Been statistics student, I fancy myself to be a Data Analyst. It's been months looking for my first entry level DA roles. But most of them need 3-5 years of experience plus tones of software skills even for junior DA. I start doubting myself. And decide to have other than DA roles jobs meanwhile up skilling myself. I still want to believe that I can make it to my dream jobs. ☺️
Thank you for this video.
Congrats dude!
Great video! I'm pretty happy that what you said is really close to my guesstimates from several experiences in small and larger companies. Another broader definition I read somewhere is about the timing of the data-related tasks, it goes: "Data Analysts look at the present and past (with Analytics), while Data Scientist look at the future (with AI & predictions)", or something like that.
This is interesting. And, yes, you're so cool and have made vivid explanation.
Good job.
