Your explanation is excellent. I really appreciate your teaching method and enjoyed. Thank you very much sir

[beboldbored]

The formula for Standard deviation used here is quite different. Its £(x- x(bar))squared divided by n-1 and then to find its square root. You just divided it with n.

You make it so easy. Thank you so much, Sir!

[AyuJessieM]

thank you very much Sir, your explanation is very crystal clear

[quietstorm]

Mr. Anil Kumar I just want to say thank for your video :)

[lakshithaudugama]

Thank you sir. Your vedio help to my academic

[omprakashtiwari]

Sir I have seen formula for SD=(x-xbar/n-1)^0.5 but you use in denominator only n, which formula for SD, one should be followed

[josephaderigha]

Thanks Sir your the best...
This video has helped me alot and am highly grateful sir..

[dalianamanda]

This was super and how can we calculate stanine?

[wrylish]

for the ungrouped data, do the mean and standard deviation values are always 0 and 1 respectively?

I have a academic problem here, and the mean and SD are not stated.

[Pinkgirlnica]

sir what if the mean of the z score is not zero what would be the method to get the mean and standard deviation of the z scores

[jenniferdaly]

can you add the formulas here so I can copy and paste them when showing work

[amnachoudry]

can u make a video on how to find the IQR and median for group data and how to make its box and whisker graph?

[mallninja]

You _showed_ z-bar is 0 but how to _prove_ z-bar is 0?

[demitrixx]

Can a mean from the z scores be a zero? Despite having another set of given raw scores different from your sample here sir? I was wondering since I solved mine and its also zero.

[anojangnaneswaran]

bro your video is nice but please cut mistakes and upload

[SunitaSharma-ffvh]

Help me to convert raw score to sten score

[theeditlover]

thx for sharing your knowledge Sir, is it possible to calculate Z-Score within the range of -50 to +50?
If so kindly share video

Why some people use square root of 76/N- 1?
