Calculating the variance with a TWIST!
Hello! I am trying to understand this problem! its just on my practice questions and Ihave the answer, I CAN NOT understand how to set it up! PLEASE someon ehelpo!
THis is it :)
A student wants to calculate the variance of a set of 10 scores. But he doesn't have hte raw scores, but only has the deviation of each raw score from the mean. Worse yet he only has 9 of tese deviation scores...
compute the variance for him
-5, +11, -4, -2, +7, -8, -6, +1, -3
