4. an organizational psychologist measures levels of job satisfaction in a sample of 30 participants. to measure the variance of job satisfaction, it is calculated that the ss = 120 for this sample. a. what are the degrees of freedom for the variance? n= degrees of freedom (df): value - 1 the degrees of freedom of an estimate of variance is equal to n-1 the "n” refers to the number of observations formula: 1) sample size of n = 30 / value or ss/n = variance 2) ss = 120/30 = 4 (df) 3) 30-1= 29 degrees of freedom
