The six numbers below are drawn from N(26, 2.5). Compute by hand their standard scores. (Just type in your answers; remember, by-hand calculations need not be shown.)
Z = (X -- mean)/sd
=(X - 26)/2.5
X | z |
27.5 | 0.6 |
35 | 3.6 |
28.5 | 1 |
31 | 2 |
23.5 | -1 |
25.5 | -0.2 |
b)
we see that as number increase, z-score increase
if number is more than mean, z-score is positive where if number is less than mean, then z-score is negative.
