Consider the following IQ data obtained from a sample of 25
incarcerated youth. Convert the 25 raw adjustment scores to
standardized scores. Show work for at least one of the 25 scores.
(Hint: You need to calculate the mean and SD first!) (4pts
for entire column) *For this question, only TWO decimal
places are required.

5. a) Using the following data, compute the z-scores for raw
scores of 20 and 25. Data: 19, 26, 18, 16, 21, 18, 26
b) Using the data in #5, calculate the true standard error. Your
parameters are µ=18.6; ?? = 4.50; N=7. What does this value
indicate about the data?
