a. examine the data to see whether there is a correlation between the pretest and the posttest scores on the PTSD scale
b. examine the data to see if there is statistical significance
c. examine the data to see whether there is statistical significance of the mean difference and whether the posttest scores is higher than the mean of the pretest
d. examine the data to compute the average of the posttest score only
