- Опубликовано: 22 авг 2024
- Standard deviation and mean absolute deviation are used in statistics to measure how far apart individual data points are from the average or mean. In this video we will understand these two concepts by taking a simple example of math and history test scores.

It only took you 8 minutes. Voila! Some teachers unable to explain in 8 years
Sir...after 32 years of my age I understood standard deviation today🤪👍
You are an idiot if you still require to learn this bullshit
Thanks for clearly explaining the difference between the MAD & SD. Also explaining the necessity for SD made this video stand out!!
I am ready with my notebook, pen and laptop :) cant wait more ....:)
I have not seen such a nice explanation of significance of standard dev. Thank you
Glad it was helpful!
You are an absolutely brilliant teacher, this video is most likely the best explanation of standard deviation on this platform
Struggling to write a lab report and this really helped. Thank you!
So happy to see that you're making videos related to data science keep it up.
One of the best vdo that explains standard deviation so correctly..i love your content ...keep making such vdos...
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.
Thank you for a great example! First time I fully understand what the concept and math are all about
Never been more excited to learn Maths and Stats
found exactly what i was looking for. Thanks sir.
I was struggling to understand standard deviation and this guy taught me in 8 min
SUPERB VIDEO! Really appreciate it!!
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.
Your presentation is so good and makes the concert simple
Good Shyt. Thanks for explaining the formation of the formula. That's where Indian teachers fail.
Imagine heart from @codebasics
Beautifully explained ❤❤❤❤❤
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
Better than any other videos on youtube.
Sir Thank you much. I have no word to explain my love for your videos.
The best explanation so far, I found on the RUclips. Thanks,
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 ✌❤
really thanks for these videos. i learning too much knowledge for data science and i developing my english.
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 :)
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;
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.
00:03 Mean Absolute Deviation and Standard Deviation measure the spread of data points from the average.
01:05 Standard Deviation measures the spread of data points from the average.
02:10 Calculating standard deviation helps understand the spread of data.
03:18 Mean Absolute Deviation (MAD) measures the spread of data points.
04:24 Mean Absolute Deviation (MAD) may not accurately represent data distribution.
05:19 Standard deviation measures the spread of data points.
06:27 Standard deviation is an important concept in data science and statistics

absolutely awesome explanation!! Thank You!
sir You understand very well 😊😊
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.❤️
What a beautiful and simple explanation. I always faced problem in SD. But now I'll never forget. Please increase video upload frequency.
👍☺️
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 very much...cleared all doubt...
These contents should have much more views !
Love it killer explanation
Really helpful 👍
Clearly explained...Thank you so much
seriously,
well explained
very clear explanation. thank you so much
This video is really helpful. Thank you sir
how easily you made the concepts clear!!
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.
Yes please!!!
most comprehensive video explanation on Standard deviation. ✌️👌👍👍
Glad it was helpful!
Finally after years, I got it
Great job
That helped me understand! Thank you!
You are a Simple style Super star.
I am happy this was helpful to you.
Really love for what you contribute to data science field !!!
A Perfect Explanation. Thanks.
good job and good explaination
I'm curious to know when you will release your data science course?
Very help full
Made easy to understand 👍🏻
4:26 but the mean shouldn't be 70 on second distribution..
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
Brilliant as usual
Thank you, sir. easy to understand.
Thank you so much 😊
OH MY GOD , ALL THIS TIME I WAS THINKING WHY THE PUCK SHOULD I LEARN STD, THIS CHITS DOESN'T HAVE ANY REAL LIFE IMPACT.AND NOW I SEE YOUR VIDEO x.X
thanks a lot sir
Very nicely explained
Thanks for liking
Fantastic explanation
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 ?
Tq very much sir !!
Great Explanation
Glad you liked it
Thank you so much sir.....
Thanks a lot for this great information...
Thanks for the great explanation 👏🏼👏🏼👏🏼🙌🏼🙌🏼🙌🏼
Super useful 👏🏼
Wonderful explanation 👌
Wow sr great explained, in-depth fundamental why we do sqare and why we need standard deviation instead of mad🙏👍
Glad it was helpful!
Great and simple explanation
Glad it was helpful!
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.
Good revision for individuals & well explanation between average, Mean average deviation (MAD), and standard deviation. The video would have been called perfect if the last 5 min (formulae) elaborated, for beginners, it can be difficult to comprehend from different fields.
example: submission steps - how do they look on board?
PS. Totally understand time constrain & just referring to your previous videos the way depth of explanation.
Thanks 😊
thank you sir. it's very very clearly explained.
Glad it was helpful!
Sir you are a awesome teacher 😀
Glad it was helpful!
Thank you
Thank you very much for very useful video clip .
Glad it was helpful!
Please keep posting videos of this series
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
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.
Good job, Sir!
Glad it was helpful!
I'm waiting for new video in deep learning playlist sir
Nicely explained 👌
Glad you liked it
do complete statistics videos
Thanks
Hii!!! I have a doubt that here we have taken 2 data set, So that by comparing we told that one data set have more scatter from mean. What if we take one data set, how can we know we have more scatter from mean(If exsist) ??
Is it right that division of M.A.D. and standard deviation gives arithmetic mean ?
If yes, please explain
very nice explanation with pictorial representation
can u pls make complete statistics playlist
many many thanx Sir
Sure I will
Thank you for your amazing videos
Glad you like them!
Ur my god sir
sir I 13-year-old I saw your how to learn coding video in that told to learn in khan academy so I start learning in that website, in that website I start learning computer principals in computer principals I understood and finished first 2 lessons but I can't understand the Limitations of storing numbers lesson please explain me this lesson I was very frustrated you told that anybody can learn to code but I can't complete a 3 lesson please help me
tech lover don't get frustrated. Skip storing numbers lesson and move on. One good strategy is to skip topics that take more time, move on and revisit those topics later
Great content 😍🙌🏼
Glad you liked it!!
thankyou
