While Arriving at the Variance of the Sample, We Divide by (N-1), Why do We do So ?

While arriving at the variance of the sample, we divide by (N-1), why do we do so?

For calculating the variance we divide by n-1 , why do we do so and not by n, please explain

ONE THOUGHT ON “WHILE ARRIVING AT THE VARIANCE OF THE SAMPLE, WE DIVIDE BY (N-1), WHY DO WE DO SO ?”

HI
N-1 case is used for samples variance calculation..
Thanks
