How to calculate reverse of Mean.

  1. Nov 19, 2008 #1
    Hi guys,

    suppose that we have list of numbers

    83+115+156 = 354

    mean = 354/3 = 118

    how can we get reverse of that .

    Can recover the above three numbers (83,115,156) from 118 by doing some mathematical tricks ( subtraction/ addition) etc.

    No, because you've destroyed some of the information. The mean of (83, 115, 156) is the same as the mean of (118, 118, 118), which is the same as the mean of (0, 118, 236)...
