    +Pinky Chan Hi Pinky! That is the problem with the covariance...its interpretation is limited. It can only really tell you that a relationship is positive or negative (based upon whether it is a positive or negative value). BUT...you can use the covariance to figure out the correlation coefficient, which tells you much more.

    Hi Sir! Thank you a lot for your very interesting videos :) I am a little bit confused by the fact that sometime one devides by n sometime by n-1,how can we distinguish the diference between the two; i mean when do we have to divide by n only or by n-1?

    KINE KINE adding to that, samples are usually not a perfect representation of the population, hence there is more chances of the answer being slightly inaccurate. So to be on the safer side we divide by n-1 because DIVIDING by a SMALLER number gives you a BIGGER end result. which just means that you have a larger co-VARIANCE now. and since ,more variance = more fluctuations in data , we end up covering a larger risk than what we would have covered otherwise if it was divided just by 'n'.
