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.

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

Thank you for the guidance

[@ishratbhat7676]

Very well explained.. Thanku

[@saraasare699]

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

[@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

Now i have understand it better thanks for the video

Glad to hear that

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

Is mean deviation and mean absolute deviation same formula?

[@ESTHERSESENU-cq5er]

Thank you very much

[@OninabResources]

You are welcome!

[@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.
Warm regards.

perfect explanation ....thank you

[@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

[@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

ohhhh cuz theres no median okay okay

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

[@OninabResources]

They are both correct since statistical parameters are just approximate values

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