Statistics: Mean Deviation, Standard deviation and variance of ungrouped data 

I have been out of college for decades and i am returning soon . I needed this tutorial to brush up on my math as i will be taking Statistics and Probability courses and of all the ones i reviewed i find Mr. Oninab to be superior in his method of explaning Thank you Mr. Oninab

2 months after my last post and thanks to your tutorials I am maintaining a high score on my Statistics and Probability college class. Keep the lessons coming in. You do the best job at explaining math with your technique

Am i the only one who is still in school and watching this 😂 😅

Thank you so much, now I can answer median deviation. God bless you

Now i have understand it better thanks for the video

Thanks for making statistics easier

That variance is supposed to be n-1 if am not mistaken

You are the best!!!!

Very well explained.. Thanku

I love your teaching

Thnk u for this clear explanation sr❤️

Thank you for your effort to make this video it help me a lot its very clear and understandable ❤❤

Thank you for the guidance

Am getting everything ... Thanks tutor

Is the variance formula not suppoaes to be n-1 at the bottom for ungrouped data??

well articulated and easy to follow

Well explained

Best video on stat❤️

Thank you very much

Great explanations but pls which one is the standard deviations is it the f(x-mean)

Thank you

Good evening sir, can you please post tutorials on Regression and Correlation analysis. Thank you.

Oh so if we are gonna find the ungrouped data of variance and standard deviation we will need a table??

Thanks

thanks

i dont know but i think we need to place them in the table in ascending order or is it not really needed to be in ascending order

Please why did you rewrite that / x - x bar/ into another coulomb without the negative sign While in finding mean deviation for grouped data I don't rewrite it. I only multiply it by the frequency to get my submission of my mean

Thank you sir

Thank uuu sir ❤❤

Is mean deviation and mean absolute deviation same formula?

really like it cong

Why look for problem! 🤣🤣😂 I understand, thank you!

second semester 200 level ,I miss exam as a result ,in hand out it was written introduction to Nsc socialogy 1 but in exam time table it written PHs 204 it make me miss a paper

It would be nice to create a tutorial on pearson product moment correlation. Your tutorial is easy to understand

Please can we also arrange the x values in a chronological under the x

Please is it necessary for us to calculate the x minus x bar before taking the absolute value of it again or we can just take the absolute value of it once

Good

perfect explanation ....thank you

Please with this question is it not a sample question because it says 10 out of

It was great

How about grouped data

So bright

Thanks alot❤

n-1, not n, in calculating variance and standard deviation

good

👌👍👍👍

So sweet

Wow

Ty pi

Bust bust bust 🎉

In mean deviation vlaue is 20 but u write 25 which is wrong....

Please why didn't you make the denominator of the standard deviation n-1 but rather n. Is it for population

Reang

Oh God statistics ehhhhhhhh 😂

You didn't say n_1

Must be n-1

You n is wrong

Thanks

Thank you

Thank you
