(a) Now, select cases of participants whose GPA is greater than 3.00. (5 pts.) (b) After you have selected cases of GPA greater than 3.00, find the descriptive statistics for the variable GPA. Include the mean, median, mode, standard deviation, variance, minimum, and maximum. (6 pts.) Upload output file.

Use the data set highschool.sav to answer this question. We are interested in whether GPA increases or decreases as students progress through high school. In order to examine this question, we obtain GPAs from 24 children at age 15 (GPA15) and then the same children again at age 17 (GPA17). Do students’ GPAs change significantly between the ages of 15 and 17?  Perform a paired-samples t-test to evaluate this question. Upload your output file showing this test.

Use the data set smoker.sav to answer the final three questions. A researcher is interested in whether regularly smoking marijuana would affect digit-span recall, which is a measure of short-term memory. The researcher first found two groups of participants (‘smoke_group’): (1) nonsmokers and (2) smokers. Each group was given a digit-span test, and the number of digits recalled is listed in the ‘digit_span’ column in the Data View. A higher digit-span score implies a better short-term memory.
