Putting these findings in standardized terms, for each standard deviation increase in a student's ACT score, we expect a .371 standard deviation increase in that student's final grade. Similarly, for each standard deviation increase in a student's GPA, we expect a .325 standard deviation increase in that student's ACS score; male students had ACS scores that were an average of .266 standard deviations higher than female students; students who were one standard deviation older tended to achieve ACS results that were .100 standard deviations higher than younger students did; and students in the treatment section had, on average, a .070 standard deviation advantage on the ACS exam
