Sir,but if we check the formula for ungrouped it is not corresponding you are using one for grouped data.

Yes missed one digit on the calculator. But methods are all correct,
@davidmichelo38143 ай бұрын
Am new to this method on finding the variance are you not supposed to use the same method used when finding the mean, but to only square them eg 0(1)²+3(2)²+3(3)² just like that then divide by the total number of frequency which is 20.
