Hi everybody, with my hope that I can get the answer here, I send you my question. When I'll get the SD in a data, why do I use the square of the difference between average and the respective value instead of the absolute value of the difference?
why root (sigma (average - x(i))^2) ? why not sigma |average - x(i)| ? thanks . . ================================================================= Instructions for joining and leaving this list, remarks about the problem of INAPPROPRIATE MESSAGES, and archives are available at: . http://jse.stat.ncsu.edu/ . =================================================================
