WAS LITERALLY ABOUT TO COMMENT THIS lowkey kinda mad that I woke up for an 8am lecture and felt really lost and confused and then watched this video and now I understand like why am I
@@alenjose3903 Thanks for that. Khan is not a statistics teacher and teaches like a maths tutor which is quite different. I really appreciate it when people can see the difference.
Thanks a lot! Great statement for clarification at 4:19 about CI : "This is not the interval that will hold the weight of 95% of the apples in the orchard: It is the interval that we have 95% confidence will contain the true value of the population mean"
This video teaches the more traditional way to calculate confidence intervals. It still concentrates on conceptual understanding rather than mathematical methods.
@@swalihashanu5827 This is not a term I am familiar with. It is a confidence interval for a mean based on a t distribution. Not sure what they mean by "exact"
Quite right Mohammed! Sometimes Khan's instructors over explain and fail to stay on point with the subject matter. The result is that I walk away more frustrated and confused than I did before watching the video! Dr. Nic keeps it simple and plain; the way I like to learn!
Epic approach to teaching, keen knowledge of learner needs, and effortless ability to teach complex concepts simply through common sense illustration. Respect for Dr. Nic!! So helpful, thank you.
You are a life saver. I hope you will continue to do this great work for years to come. i have been going through tons of tutorials and I find this refreshing. taking a data science course.
I love when math is explained in more intuitive terms, focusing more on meaning and "connecting the dots" rather than strict deriving forumula after formula (even though its also needed), well done!
Honestly learned more about CIs in your two videos than an entire 4 year undergrad in biological sciences - It is taken for granted that you just know these things. Thanks for a well explained video.
@@DrNic If you can't explain it to a 6-year-old, you don't understand it yourself. Reminds me of this. Your videos have saved me some embarassment. lol.
GREAT VIDEO. REALLY HELPS TO UNDERSTAND CONCEPTS BEHIND CONFIDENCE INTERVAL. THE ENTIRE TEAM OF Statistics Learning Centre IS TO BE CONGRATULATED. WISH TO CONTINUE THEIR ENDEAVOUR IN SIMPLIFING STATISTICAL METHODOLOGY
This was well explained and easily understood video. I am doing an online course, and this helped me understand the material so much better. THANK YOU!!
Thank you so much Dr. You are the best teacher. I have learned alot in your demonstration. Now i have cleared concepts about confidence interval and point estimator, standard error of mean and t value.
That is great to hear. You probably had most of the ideas already and this video helps to organise them for you. Good luck in the rest of your studies. You can find our videos organised here: creativemaths.net/videos/
Richard Funman is right. "If you cant teach it you dont understand it". We had poor teachers in our medical schools. I saw few UA-cam videos worth a lot. Thanks.
statistics is actually so simple once you understand the concepts. some teachers bounce around too much and fail connect or distinguish different means and sds which is what my classmates and I struggled with.
It's true - there are just a few concepts to understand, particularly around samples and populations and once you understand them, the rest is mainly mathematics which can be done using a computer.
Oh Thank you so much. I have spent a long time trying to understand my professor. Now I finally understand what he was trying to say but couldnt really communicate.
Your videos are remarkably clear. Much better than many lecturers' I've had. Just a quick comment/question: my Harvard graduate Ph.D. in Epidemiology big head professor told me that I shouldn't make the assumption that "we are 95% confident that this interval contains the true value of the population" because this definition only applies when we are thinking of a hypothetical infinite number of samples (re-sampling/frequentist statistics approach) but never to any specific sample alone. Therefore, the explanation of minute 4:34 would be correct based on what he explained to me, but what you said a few seconds earlier (in minute 4:25) would be imprecise due to this technicality because we can only say this when we are considering broad re-sampling (but never for our single sample). Would you say that he might be correct when saying this? Thanks a lot. Your contribution to people you want to understand statistics is truly enormous with such clear videos!
For any specific sample, providing it is random and representative of the population in question, we can say that we are 95% confident that a 95% confidence interval will surround the population mean. The explanation of 4:34 is the statistical meaning of "95% confident". We do not take more than one sample in any instance, so this is the correct interpretation of a single confidence interval. There is always a tension between very very precise definitions and definitions that are useful and useable.
On a table I refer to, for a sample size of 15 and confidence level of 95%, I get 2.131, your t value of 2.145 appears but for a sample size of 14. However, the explanation is fantastic.
Thanks. The number in the t-table is the degrees of freedom. For a confidence interval for a mean, the degrees of freedom is n-1 (or the sample size minus 1). That is why we look up 14, not 15. I realise at 2:25 this is a little confusing. At 2:14 I did put in that df is sample size - 1.
I learned more in this 5 minute video than I did in a 2 1/2 hour lecture last week, THANK YOU!
I'm pleased to hear it. It might be that it helped consolidate the lecture material. Either way it is great to help.
@@DrNic humble.

@@alenjose3903 Thanks for that. Khan is not a statistics teacher and teaches like a maths tutor which is quite different. I really appreciate it when people can see the difference.
This video is awesome. I recommend all of my professors to watch this before going to class!
😂😂
Damn bro!! Laughing so hard, I needed this :)
Yes. Lmao
So much clearer than my lecturer. Thanks.
"You can read it from the table" *shows actual table
Showing the actual table is incredibly helpful for us visual learners! Thank you!
I do not know how much time it would had taken to understand without this video.
Aside from the excellent explanation, I love the humor!
I have watched this video at least 10 times in the last couple of years, and each time I learn something new!
Great video!
That’s great to hear. Thanks
This video saved my life
+Henry Bidar Never thought STATS is this fun, my lecturer makes it painful but this is delightful
Thanks a lot!
Great statement for clarification at 4:19 about CI :
"This is not the interval that will hold the weight of 95% of the apples in the orchard: It is the interval that we have 95% confidence will contain the true value of the population mean"
Not all heroes wear capes. Thanks a lot. I’m watching this 4 hrs to my exam and you may have just saved me. 😂
Glad I could help!
Wow, this is one of the clearest videos I've ever seen on UA-cam, and it got right to the point. Excellent.
Thank you SO MUCH, i can finally understand the logic behind all the gibberish in my book!! Saved my life
That is great to hear - I believe yours is not the first life I have saved in this way. ;)
This video teaches the more traditional way to calculate confidence intervals. It still concentrates on conceptual understanding rather than mathematical methods.
Statistics Learning Centre always a pleasure learn from those who really know how to teach ☺️
Thank you so much , you are my hero
Does this have any similarity with 'exact confidence interval for mean based on t distribution '??
@@swalihashanu5827 This is not a term I am familiar with. It is a confidence interval for a mean based on a t distribution. Not sure what they mean by "exact"
@@DrNic oohh...I see..Thanks a lott Ma'am for the clarification
Thank you very helpful almost at a 3rd grade level with your tone of voice and examples it makes it so much easier to understand
THANK YOU SO MUCH! Aced my stats quiz thanks to you!
1000 times better than Khan Academy nonsense.
khan academy video was pretty confusing you are right .. .
exactly right
Quite right Mohammed! Sometimes Khan's instructors over explain and fail to stay on point with the subject matter. The result is that I walk away more frustrated and confused than I did before watching the video! Dr. Nic keeps it simple and plain; the way I like to learn!
true that!!
Khan academy exists just because it needs to exists! No purpose tho.
Epic approach to teaching, keen knowledge of learner needs, and effortless ability to teach complex concepts simply through common sense illustration. Respect for Dr. Nic!! So helpful, thank you.
Thanks - It has taken several years of teaching this material to get to this point. Nice it seems effortless.
You are a life saver. I hope you will continue to do this great work for years to come. i have been going through tons of tutorials and I find this refreshing. taking a data science course.
Great to hear!
I wish you could make videos for all of my classes! You make everything so clear. Thank you.
I wish I could too! Any particular requests? ;)
I love when math is explained in more intuitive terms, focusing more on meaning and "connecting the dots" rather than strict deriving forumula after formula (even though its also needed), well done!
That is what I aim at, so it is gratifying to hear that I am succeeding.
If learning statistics is like mission impossible then you are tom cruise...............
hats off
That has to be one of my favourite comments. Thank you.
and u r my favorite teacher mam.......
....I have no words to describe your effort. ma'am, I with you love and happiness.
Probably the best video on UA-cam related to Confidence Interval!!!!!!!!!!
You are too kind. I actually think my earlier video, understanding confidence intervals is a little better. ;)
As much as this explanation was simple as much as it was complex for the creator to produce. Appreciate the well put explanation.
Thanks - it can be difficult to make things seem simple. My son did a great job with the editting too.
Thank you for clarifying what hours of reading has made seem impenetrable.
Animations and especially those of the equations is just great. Helps a lot. Thank you.
Honestly learned more about CIs in your two videos than an entire 4 year undergrad in biological sciences - It is taken for granted that you just know these things. Thanks for a well explained video.
Thank you so much, u saved my Biostatistics exam
The animations help a LOT! These videos saved me! THANK YOU!
This is the best video about confidence intervals which I could find on UA-cam !!
Thank you so much. You just saved me for my upcoming stats exam.
I know I’m late, but you are a Godsend mam. I might actually be able to pass my class because of you. Thank you so so so so much!
Been watching many statistics videos now, this one has been the only one that's made me smile xD
Explained it in so simple and understand able way. Thanks. I wish my teachers made maths so simple and interesting. Thank you very much DR Nic
Glad it was helpful!
this is great!, shocking , really. your voice and teaching ability makes it seem so simple. amazing!!!!!!
it is more helpful than my last week 2 hours online lecture
Glad to hear that
This video has one of the best explanations for CI.. Awesome
very nice presentations in all of your videos. No extra words , nothing to confuse. Definitely recommendable to others.
simple to understand certain cases... very easy... thank you, its rare to have lecturer like you to makes this video
one of the best explanation ever!
Glad it was helpful!
You, ma’am, are a huge time saver !

Words cant explain how long it takes to find a youtube video that isn't a derrick like my lecturer. Thanks heaps!
Why thank you, Tim. I hope you can use some of the other videos as well.
Helps in conceptual understanding. Really great. Thanks.
Concepts so clearly explained. Thanks Dr
You are welcome
Best statistics teacher...Thank u so much
So nice of you
Tank you for this intuitive explanation
You are most welcome. Good to hear you find it intuitive - I do aim to make it about ideas rather than procedures.
It's ABSOLUTELY AMAZING how much I understand now thanks to this video😢❣👏
That is music to my ears
very nice thanks...The part about what it is NOT is just as useful as to what it IS

Glad it helped! You were probably nearly there and the video put it all together for you.
this video is awesome! i made your drawings and schemes in my notebook, it seems so easy when you explain it. Just great!!!
These are really well done videos!
I finally got it! Thank you!
terrific lecture...i always found this to be ridiculously confusing but thanx to you guys for clearing the concept..
Thank you so much! My professor is godawful!
They're probably too stressed from their teaching job to actually do their teaching job.
I was struggling with this concept before, but thanks to your excellent teaching skills, I now have a solid understanding of it😊😊
That is great to hear. I put a lot of thought into my videos and I have had considerable experience so I am glad I can help you.
Wow one of the best I have ever seen
