In this lesson, you will learn how to find the standard deviation and the mean average deviation of a data set. We will also learn how to interpret the results. The mean of the data is a measure of the center of the data set. The standard deviation and the mean average deviation (MAD) tell us, on average, how spread the data is about the mean. It tells is the range about the mean where most of the data lies.
Statistics is harder than leaning Chinese taught by a professor speaking in Greek. However. This video, after studying it about 15 times, makes the Mean Absolute Deviation and the standard deviation clear. Not easy to understand, but clear. I get it. Finally. Thank you.
You have completely removed my fear of statistics, thank you so much sir... You are the best teacher..
Best teacher thank you for your explanation
I wish he taught every subject. This is a perfectly detailed explanation. Thanks!
Are You a Lecturer? No, You are a very Excellent One!
Thank You!
Great Lesson. Quick, easy to understand, complete and well said! Thanks
Nothing better than a great teacher like you.
Awww thanks!
@@MathAndScience 🤎🤎🤎
Life is better after this explanation. Wonderful teacher!!!!
You really are the best teacher. I will be teaching my professor to teach the class like you!!!!
you are doing a great job, thanks for the explanation!
Love this great teacher so much!!! After his lectures I understand every topic so clearly. Thank you! 🤝
Welcome!
You are the best teacher 💯
Thank you immensely! You are a fantastic teacher!
Hi man, stats makes me want to give up but you have gave me a visualise about the entire maths from the scratch thanks I would appreciate if you can do about histogram as well.
why is there also N-1 in the formule on standard deviation?
I would like to give a millions like sir!
Sir you're a star
Why did you leave out odd numbers when calculating the mean ?
The way you explain everything is really awesome 💖💖💖
Thanks so much!
It is very good session but small observation is : avg of 14|15|16|17|18|19|20|21|22| is 18
If there is any word that can describe you is " Legend "!!
Following through.
You made easy for me
That's great. I learnt. thank you, sir.
Thanks for the video, a very really clear and helpful example
when calculating variance why are you dividing by (n) rather than (n-1)?
THANK YOU... SIR...!!!
Very clear,thanks
Cheers that was well worth the watch as reminder... 👍
Is the MAD also known as confidence intervals?
Beautifully explained thanks
How can you be reached sir for questions.
What about (n - 1) concept?
Chennai.
Thankyou.
I'm grateful. How can I contact you. Need help
??? Based on the math for MAD, isn't it incorrect to say the majority of the data is within MAD of the mean? More like about half your data is within MAD of the mean?
really useful!!! thanks a lot!
Thank you
Wow video ❤
can't be simple than this
But why why why?
Why SD instead of MAD if MAD is does the job and is more intuitive and fulfills the purpose.
Great question. Just different tools. Why only make just one size knife. All knives do is slice and cut. Why all the different sizes? Makes no sense.
@@MathAndScience why? Where is the answer? which knife to use in which senario?
you are the best,,,,,,,, can i see your face sir
Awesome
I think you missed n-1 formula, so it should be 5-1.
First
😀😀👏👏👏👍
why so MAD :P
Much appreciated the simplicity and passionate breakdown @Jason
Never seen someone be so clear in explaining STD.
Beautiful lecture thanks

Naturally gifted, God blessed you sir. I will like you to be teaching me online like this, thank you
excellent tutorial on standard deviation and mean absolute deviation, thanks for sharing
Glad it was helpful!
You are execelent
Thank you so much.
Thankyou
Sir, can you explain is it 2types of formulas for SD. Devided by N-1 ?
Thank u
Congratulations 🎈🎊🎉. Great 👍🏼 lessons
Very nice. Thank you. I keep coming back to your videos.
This is great, thank you.
I've been self teaching math, your tutorials have been great
stats makes me want to cry sometimes but your video made it make sense, thank you so much king
