[@ferdost1667]

The best way of explaining Thank you soooooooo much and God bless you.

[@ArjunS921]

AMAZING! Please keep making more videos like these! I couldn't find anything more TO THE POINT like this! Thank you So much!! Keep up the great work!

[@SamuelGuebo]

Sleek and straight to the point. Thanks!

[@krishnanforfunishere]

What is the actual formula, in some problems x-xbar ,and y-ybar used.in another problems directly squared x and y.pls clarify

[@thebrahmos7703]

best short and to the point video!!! Really thankful

[@Rishabsmusic]

thank you sir

[@priyankakhatwani6182]

[@9135100004]

Very helpful clear all my concept

[@dharshinim]

In Macmillan book different formula is used..but you are telling different formula..which one is correct

[@mrinmoynegel1036]

isnt the formula for variance= (x-x")^2/n-1 instead on den of n ?

[@ayansingh4421]

thanks sir for your master video on sampling numerical

[@krishnanforfunishere]

This video is good.but when applying this formula to the unsolved problems in McMillan ,the answer is different.. especially variance of X ,,Y formula ,

[@vineetkumarsharma1453]

Hats off sir you and your team

[@chris5321]

Excellent tutorial. thankyou

[@charmaineandrade4276]

thank you! its help me a lot

[@raooosivasiva6924]

you can detailed explanation in understand level by own that means 2-1 = 1 it is cleared but standard deviation is not understand at level

[@353mohit]

Thank you for the video. However, the formula for Covariance is wrong. It should be be divided by n-1 and not n. Please cross verify.

[@asdasvcxvwe5114]

i know this is an old comment but it can be confusing to some people who would come in the future so i thought i would explain it better, the Covariance formula is by @Ns Toor is correct. but you are also correct. you should divide by n in case you are dealing with the whole Population, but should divide by n-1 in case you are dealing with just a sample of the population. to the future people, you are welcome 😂😂
