Short Answer Questions For this portion of your assignment, please complete the following four (4) questions. In order to receive full marks, you must show your calculations. If you prefer to do your calculations by hand (paper and pen), please scan the assignment and save it as a .pdf or insert the images into a word document before submitting it. Question 1 (10 Points) There is some evidence that students who use Facebook while studying tend to have lower grades than non-users. A representative study surveyed students to determine the amount of Facebook use during the time they study or do homework. Based on the amount of time spent on Facebook, students were classied into three groups and their scores on a 10-point test were recorded. The following data show the results: Non-User Rarely Use Frequent User 4 1 0 6 4 2 G = 43 3 5 0 2x2 = 193 7 2 2 5 2 0 T = 25 T = 14 T = 4 SS = 10 $5 = 10.8 $5 = 4.8 Use an analysis of variance with a = .05 to determine whether these data indicate any signicant mean differences among the treatments (Facebook user groups). Remember to; Use an analysis of variance with a = .05 to determine whether these data indicate any significant mean differences among the treatments (Facebook user groups). Remember to; 1. State the null hypothesis, 2. Show all of your calculations, 3. Make a decision about your null hypothesis, 4. Make a conclusion including an APA format summary of your findings (include a measure of effect size if necessary), and 5. Indicate what you would do next given your findings. Question 2 (2 Points) Describe the circumstances in which post tests are used, and explain why these tests are necessary. Question 3 (10 Points) The following data were collected from a repeated-measures study: Determine if there are any significant differences among the four treatments. Use a.05 level of significance. Remember to; 1. State the null hypothesis, 2. Show all of your calculations, 3. Make a decision about your null hypothesis, 4. Make a conclusion including an APA format summary of your findings (include a measure of effect size if necessary), and 5. Indicate what you would do next given your findings.

The dependent variable is level of anxiety experienced during exams. Deep Breathing Meditation Medication High M =3 M =6 M = 9 Anxiety T = 15 T = 30 T = 45 SS = 18 SS = 28 SS = 26 Low M = 1 M = 4 M =1 Anxiety T = 5 T = 20 T =5 SS = 8 SS = 20 SS = 20 1. State the hypotheses for each of the three separate tests included in the two-factor ANOVA. 2. Draw a graph which would illustrate what means are being tested for each of the null hypotheses. 3. Calculate the degrees of freedom and state the critical value of F for each of the three tests. 4. Calculate the three F-ratios and state a conclusion for each test. 5. State what the next steps would be given the results you have concluded
