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

[@ritaallerding6802]

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

[@OninabResources]

Thank you so much for your feedback and compliment.
It means a lot to me.
Warmest regards.

[@ritaallerding6802]

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

[@OninabResources]

Thank you so much for your feedback and compliment. We are glad our videos are helpful to you. Wish you more success.

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

[@himashakularathne9544]

Thank uuu sir ❤❤

[@titusshigwedha5344]

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

[@OninabResources]

Thank you so much for your feedback.
There is no harm, you can either use n or n - 1 as your divisor.

[@tajingriyang2301]

Sir ungrouped data and grouped data of mean deviation formula is not same ????

[@OninabResources]

There is a slight difference in the formula.

[@anma690]

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

[@anma690]

ohhhh cuz theres no median okay okay

[@hassantobilobamuiz8306]

Is mean deviation and mean absolute deviation same formula?

[@saraasare699]

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

[@aChohoyrr]

Hey sir I watched your video's you teaching very very gOooD but there is a lil bit problem I can't understand you're voice make you're voice a lil bit bold/loudly that's easy to understand ❤

Thanks for your feedback, I'll work on making my voice clearer in future videos.

It would be nice to create a tutorial on pearson product moment correlation.

We are pleased to inform you @OninabResources just uploaded video on Pearson's Product Moment Correlation Coefficient as requested.

[@saraasare699]

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

[@OninabResources]

It's not necessary. I calculated it directly in the video for mean of grouped data. See the link below 👇

Ok thank you

[@christinemaemalto1680]

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

[@olatoyefrancis4575]

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

[@Legend3868]

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

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

[@OninabResources]

They are both correct since statistical parameters are just approximate values

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

[@kinmit468]

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

[@aminatsalawu33]

That's for sample standard deviation
