Write a name and letter symbol for the measure in each

Question

Use the ten step "deviation method" to compute the standard deviation for the five scores below. Write a name and letter symbol for the measure in each step. Show the computations for all steps. Compute the z-scores for the data. Show the computations

Observed Value       Deviation                 Squared Deviation

Name        X                              (X - Xbar)               (X - Xbar)²       

Alice         16                             16 - 10 = 6               6 * 6 = 36

Beth          12                             12 - 10 = 2               2 * 2 = 4

Carl           10                             10 - 10 = 0               0 * 0 = 0

Dave          8                               8 - 10 = -2               -2 * -2 = 4

Erma         4                               4 - 10 = -6               -6 * -6 = 36

Total         50                                                              80
