Question

Calculate for Z- scores 73, 14, 21, 45, 18, 74, 32, 37

Answer 1

You can surely do this! First, find the mean of the 8 given scores. Add up these scores and then divide the result (sum) by 8 to obtain the mean.

raw score - mean
The formula for "z-score" is z = -------------------------
std. deviation

You'll need to calculate the standard deviation of these 8 scores.
73 - mean
Then, as an example: raw score 73 translates into z-score z = ---------------
std. dev.
