If I know the mean and standard deviation, but I don't have an original data set, is it possible to reverse calculate a data set that has this known mean and std dev? Is there an excel function I could use to do this easily? I know there could be multiple correct datasets and that's fine, I'm just wondering if it's possible to reverse derive a correct one that has the known mean and std dev. So, for a MEAN = 100 and STD. DEV= 15, can anyone tell me how to calculate a data set with n=3? Many thanks.
