Measures of Dispersion (Grouped Data) | Basic Statistics

Clear and easy explanation of finding the range, variance, and standard deviation of a grouped data. These are what you call measures of dispersion or variation which would tell you how scattered your data is from the mean.

Like who teach you mathematics.. I'm shock , I understand without any stress.. You are amazingly good Sir

[@PinoyMathematician]

wow thank you

[@owusujoseph2757]

Measure of shapes isn't part??

[@markmartesd.rosendo8638]

Thank you very big sir, for the explaining in how to solve in grouped data, huge help for me sir😍

[@guevarramarla6578]

This helps me a lot sir, Thank you Keep Safe.

[@PinoyMathematician]

Welcome :) Thanks for watching my vid. 😄

[@princesspolo9954]

thank you po ng maramiii

[@hannaccc9881]

Thank you it was so helpful

[@edenlalaineguzarem1817]

THANK YOU SO MUCH FOR THISS

[@kristinearcos5744]

What if the given data is 1-5 6-10 11-15 16-20 21-25 Why is it the range still 25? Though I did the same process as yours.

Thank You Po dito sir napaka laking tulong po

[@aoki_ra]

Thankyouu po sir this made me understand my module in math easier♡

Pano kung zero ano yung class boundaries?

[@nonysuleman4423]

Very good

[@unknown-bx8my]

thanks:)

[@charmaeempig5744]

Very helpful, sana tagalog para madali magets

[@josephokoth6819]

thank you...when should i use N and N-1 im confused in finding variance

[@PinoyMathematician]

when the data is coming from population, then use N. when data is coming from sample, then use N-1.

[@royedbadshah8548]

Thank you so much sir

[@unknown-bx8my]

why in my course the denominator of s2 is just n and in online explanationa is n-1

[@rizmandesu]

to find the population sd or variance, the denominator is n, to find the sd and variance from sample data, the denominator is n-1

[@fridayusankurong4995]

i can't thank you enough sir. i have issues with confidence coefficient

[@rizmandesu]

for the variance, why are you using the formula for ungrouped data?

[@PinoyMathematician]

Those formulas are all for grouped data. Im just using formula for sample since it's the most common and practical.

[@Anitha2076]

Why we take 9.5 & 12.5

[@Miyoji]

hanggang ngayon nalilito ako dito hahahaha nilalagyan ng .5 yung highest tapos -.5 sa lowest

[@emmanlovesart2377]

i thought the N is the number of values

[@PinoyMathematician]

That's for ungrouped data. 😅

[@mohamedhassanmohamed944]

hhhhhhhh what wrong calculation is! might be his pocket and pursuing to get click a lone

[@SittieAinnaAUnte-xv9xk]

Wrong yung range, it should be 21.5 - 12.5 which is 9

[@Miyoji]

hanggang ngayon nalilito ako dito hahahaha nilalagyan ng .5 yung highest tapos -.5 sa lowest
