Standard Deviation & Mean Absolute Deviation Explained - 6-8-19]

More Lessons: www.MathAndScie...
Twitter: / jasongibsonmath
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.

Cheers that was well worth the watch as reminder... 👍

[@aloismakau8703]

Awesome

[@beenay18]

But why why why? Why SD instead of MAD if MAD is does the job and is more intuitive and fulfills the purpose.

[@MathAndScience]

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.

[@beenay18]

@@MathAndScience why? Where is the answer? which knife to use in which senario?

Never seen someone be so clear in explaining STD.

[@CpJohn-zu5xb]

Beautiful lecture thanks

[@wilkovisser5384]

why is there also N-1 in the formule on standard deviation?

[@odunola1234]

Awesome explanation, you're a great teacher...

[@madebyhan]

I wish he taught every subject. This is a perfectly detailed explanation. Thanks!

Naturally gifted, God blessed you sir. I will like you to be teaching me online like this, thank you

[@terencewright2223]

I can't thank you enough for making it so clear. Excellent video.

[@MathAndScience]

Thank you!

[@MariaAyakMaluac]

Why did you leave out odd numbers when calculating the mean ?

[@lynnedipadua7006]

Thank you immensely! You are a fantastic teacher!

I'm grateful. How can I contact you. Need help

How can you be reached sir for questions.

[@dharmadasawedagedara6888]

Sir, can you explain is it 2types of formulas for SD. Devided by N-1 ?

[@voticiano]

I would like to give a millions like sir!

[@mrchin7562]

??? 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?

[@tamiratgebremichael9794]

You are execelent

[@rahil1970]

What about (n - 1) concept?

[@ProviderKnowledge]

That's great. I learnt. thank you, sir.

[@marykimuyu3103]

Very clear,thanks

[@242math]

excellent tutorial on standard deviation and mean absolute deviation, thanks for sharing

[@MathAndScience]

Glad it was helpful!

[@sivakoti9799]

It is very good session but small observation is : avg of 14|15|16|17|18|19|20|21|22| is 18

[@tresajessygeorge210]

THANK YOU... SIR...!!!

[@a.sathyajothi2580]

Thank you so much.

[@phil97n]

This is great, thank you. I've been self teaching math, your tutorials have been great

[@EPHRAIMMWANGIKINYUA]

when calculating variance why are you dividing by (n) rather than (n-1)?

Thank u

[@tjamwal4587]

I think you missed n-1 formula, so it should be 5-1.

[@bexxappeal]

stats makes me want to cry sometimes but your video made it make sense, thank you so much king

Is the MAD also known as confidence intervals?
