Lab Details

Your submission for this Lab Assignment should be a Jamovi file with a .omv extension.

Create a variable called Average Exam Score that is the average of exam scores 1, 2, and 3. Use the compute mean command to do this.

Transform the Motivation Variable into Motivation Groups with 3 groups: Low (1-3) Medium (4-6) High (7-9). Use the layered IF command to do this.

Create a frequency table for the residence variable.

Use the descriptive statistics function to find the mean and standard deviation of the life satisfaction variable split by 2 variables; extra-curricular involvement and Motivation_Groups. Report each mean and standard deviation and provide output.

Find the mean and standard deviation for exam 1, exam 2, exam 3, and average exam scores variables.

Compute histograms with a normal curve (density) for average exam scores and life satisfaction scores.

Create a histogram without a normal curve(density)for exams 1, 2, and 3.

Split the data by the motivation groups variable and find the mean exam score and life satisfaction score for each group as well as the histogram and density for each group.

 Dr. Rose was interested in studying student involvement in extracurricular activities, residence, school motivation scores, life satisfaction scores, and their scores on exams 1, 2, and 3. He found that students were either (0) not involved with extra-curricular activities on campus or (1) involved with extracurricular activities, and either lived (1) on campus, (2) off-campus, or (3) with their parents. Below are data from participants on each of the variables.
