Nice explanation. I am looking for exact meaning of standard deviation. Very useful, I am studying 3rd year MBBS, I am looking for this topic which is coming under Biostatistics of Community Medicine.
Thank you for explaining the concept. Everyone know the equation of variance, standard deviation and how to calculate it. But my question was what does this number actually means? This video explains it well.
Just came across this. Maybe someone has already mentioned it but the absolute value for Abdul is incorrect. Abdul has a score of 73 and the average is 70 making the absolute value of Abdul's score minus the average 3 not 2. Disappointing that the work was not checked before publication. Stopped watching at 3:33.
5:31 if i add few more person with 70 mark then even stander deviation again become near to mean deviation so how it is full proof concept thus in that case variablity is compare by coefficient of variance
Thank you very well explained and easy to follow; I think when that famous man was once quoted in saying "if you can't explain something in simple form maybe you don't understand it yourself" he was thinking of you. Good simple explanation ! ps: that was Einstein I precision shoot rifles and the SD now is a big issue and discussed when collecting an array of numbers. Only question I ask now is when someone says the SD is very low for a set of target hole variations calculations I ask compared to what ? No-one has an answer for that.
Thankyou so much for making python and power bi courses, I purchase it, and I really like it. I learn real time project how to be done in the company. Now, I have confidence that I can do something in this field. Can You make a course for how statistics use in data science? It would really help us. Thankyou in advance.
Hi @codebasics. Very nice explanation about MAD and SD. What happens if we use SD when the data is not normally distributed. At 7.33 minutes it states that using SD has nice properties. What are those nice properties?. A step-by-step method on when to use SD and when to use MAD on data points will be helpful. Thank you :)
Sometimes we describe MAE in terms like 'The overall mean absolute error (MAE) of the 49 subjects was 0.911 ± 1.65.' Can u plz explain what does that mean of +,- with some number
How can I find mean and variance of probability distribution using python? I have mentioned a problem below. Thanks in advance! The number of times I go to the gym in weekdays, are given below along with its associated probability: x = 0, 1, 2, 3, 4, 5 f(x) = 0.09, 0.15, 0.40, 0.25, 0.10, 0.01 Calculate the mean no. of workouts in a week. Also evaluate the variance involved in it.
Thanks so much for this video, it made the concept a lot clearer. I do have a question however, I don't know if I'm miscalculating but for the 4th table, wouldn't the score avg. be 71, which would change the MAD to 4? Because if you add up the scores (83+70+70+63+70+70), you get 426, divided by 6 (number of students), it's 71. Right?? Or am I missing something? And then for the abs. column it would change to: 12, 1, 1, 8, 1, 1; that totals 24. 24 : 6 = 4 for our MAD. Could somebody verify this or explain where my logic is off please?
Thank you guru very nice explanation I'm getting the difference between variance and SD all peoples simply said with square root and w/o square root...but i actually need the layman terminologies of both variance and SD
Excellent content, I am searching for Machine Learning course on your platform, but I think Machine learning course is not there yet, Is there live training on Machine Learning and Data Science Available ?
I have not seen such a nice explanation of significance of standard dev. Thank you
Glad it was helpful!
Sir...after 32 years of my age I understood standard deviation today🤪👍
You are an idiot if you still require to learn this bullshit
Nice explanation. I am looking for exact meaning of standard deviation. Very useful, I am studying 3rd year MBBS, I am looking for this topic which is coming under Biostatistics of Community Medicine.
Struggling to write a lab report and this really helped. Thank you!
I am ready with my notebook, pen and laptop :) cant wait more ....:)
One of the best vdo that explains standard deviation so correctly..i love your content ...keep making such vdos...
It only took you 8 minutes. Voila! Some teachers unable to explain in 8 years
Talking abt 😂 indian schooling
4:26 but the mean shouldn't be 70 on second distribution..
Thanks for clearly explaining the difference between the MAD & SD. Also explaining the necessity for SD made this video stand out!!
You are an absolutely brilliant teacher, this video is most likely the best explanation of standard deviation on this platform
Never been more excited to learn Maths and Stats
So happy to see that you're making videos related to data science keep it up.
Thank you for explaining the concept. Everyone know the equation of variance, standard deviation and how to calculate it. But my question was what does this number actually means? This video explains it well.
Sir Thank you much. I have no word to explain my love for your videos.
Thank you for a great example! First time I fully understand what the concept and math are all about
Just came across this. Maybe someone has already mentioned it but the absolute value for Abdul is incorrect. Abdul has a score of 73 and the average is 70 making the absolute value of Abdul's score minus the average 3 not 2. Disappointing that the work was not checked before publication. Stopped watching at 3:33.
Your presentation is so good and makes the concert simple
The best explanation so far, I found on the TH-cam. Thanks,
I was struggling to understand standard deviation and this guy taught me in 8 min
awesome! I never understand what is SD before
really thanks for these videos. i learning too much knowledge for data science and i developing my english.
Better than any other videos on youtube.
SUPERB VIDEO! Really appreciate it!!
Thank you sir it's very easy to understand with an example. It would be great if you'll do more insights on Hypothesis testing as well.
Agree.
What a beautiful and simple explanation. I always faced problem in SD. But now I'll never forget. Please increase video upload frequency.
👍☺️
Imagine heart from @codebasics
Thank you very much...cleared all doubt...
found exactly what i was looking for. Thanks sir.
Good Shyt. Thanks for explaining the formation of the formula. That's where Indian teachers fail.
Great video understood easily
Clearly explained...Thank you so much
Beautifully explained ❤❤❤❤❤
You are a Simple style Super star.
I am happy this was helpful to you.
absolutely awesome explanation!! Thank You!
5:31 if i add few more person with 70 mark then even stander deviation again become near to mean deviation so how it is full proof concept thus in that case variablity is compare by coefficient of variance
seriously,
well explained
sir You understand very well 😊😊
Awesome Explanation, just loved it. Very simply explained. Why can we have the same in college/universities !!!
Thank you very well explained and easy to follow;

These contents should have much more views !
very clear explanation. thank you so much
Love it killer explanation
7:47 So standard deviation is nothing but euclidian distance?
This video is really helpful. Thank you sir
Really helpful 👍

Yes please!!!
Made easy to understand 👍🏻
Sir you are a awesome teacher 😀
Glad it was helpful!
Sir the words are not enough to appreciate your efforts... but first teach us how to stay calm nd compose like you while doing work :)
Smoke weed
Very nicely explained
Thanks for liking
good job and good explaination
A Perfect Explanation. Thanks.
how easily you made the concepts clear!!
Fantastic explanation
Really love for what you contribute to data science field !!!
Brilliant as usual
Great and simple explanation

Can u plz explain what does that mean of +,- with some number
Great Explanation
Glad you liked it
That helped me understand! Thank you!
6:39 as far as ik it should be N-1 right?
nope thats only when you do it for sample variance ( unbiased variance )
@@muhammedjaabir2609 how would someone know if it's a population or sample variance?
Wonderful explanation 👌
most comprehensive video explanation on Standard deviation. ✌️👌👍👍
Glad it was helpful!
Thanks a lot for this great information...
Great Tutorial, I know now what is Standard Deviation, but why should I know how far the data are from average, I mean what is the use of it?
The use of it is to removal outliers
@@codebasics so the higher the number the more outliers we have?
Thanks ❤
Thank you so much 😊

I'm curious to know when you will release your data science course?
You're such a nice person talk maths extreme politely since maths is explicit for me 🔥.I wish this channel reach a good stand on yt.❤️
Thank you so much sir.....
Yeah there is Stat quest, there is Luis Serrano but don't forget in the same line there is Dhaval sir...!!!
Mit liebe aus Deutschland ✌❤
Thanks 😊
thanks a lot sir
Wow sr great explained, in-depth fundamental why we do sqare and why we need standard deviation instead of mad🙏👍
Glad it was helpful!
Please keep posting videos of this series
Thank you for your amazing videos

Best vedio
do complete statistics videos
Thank you
Hi do you implement any hybrid machine learning models? collaborative filtering, rule based classification, and association rule coding...
Is it right that division of M.A.D. and standard deviation gives arithmetic mean ?
If yes, please explain
