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

[bktechnologies]

You're the best teacher I've ever know
You take things step by step
Normally I hate statistics but you making me like it I give you a thumbs up keep up the good work❤❤

[maposampho]

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

[HeavenlyNancy]

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

[GabrielCholMading]

Now i have understand it better thanks for the video

[Universal.lover.]

Thnk u for this clear explanation sr❤️

[alexandraaneke]

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

[robertoqdomimgo]

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

[mpapaleveronicanamasaya]

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

[jamesmakau]

Am getting everything ... Thanks tutor

[hassantobilobamuiz]

Is mean deviation and mean absolute deviation same formula?

[nidhiiiiiiiiii]

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

[titusshigwedha]

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

[Legend]

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

[christinemaemalto]

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

[anma]

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

[olatoyefrancis]

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

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

[saraasare]

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