well to do this you need to know the mean.... as an example if the mean is 10 and the 1st value in the table is 15 $x_{j} - \mu = 15 - 10$ does that make sense...?

3. zarkam21

Yes but that would be for the first column right??

that's correct. the 2nd column just square the value in the 1st column. then sum the 2nd columm
