Use of SPSS for Psychology Experiment

SPSS Review HW #5 Use SPSS to answer the following questions.
1. From a General Psych class, 40 snake-phobic students were selected and randomly assigned to one of four groups. Group 1 received five sessions of relaxation training; Group 2 received five sessions of imagery training (they imagined several fearful situations); Group 3 received relaxation training and imagery training together; Group 4 received no training at all. Three weeks after, they were given a behavioral avoidance test to determine how close he/she would approach a live snake. The response measured is the distance from the snake in feet. Here are the results:

a. Write a brief results and discussion section for this data in APA style. Use a Scheffe post-hoc test if necessary. Include the effect size statistic in the results sentence if appropriate for this test.
2. You are hoping to improve the free throw shooting of the U12 girls basketball team that you coach. You ask the girls to keep a record of the number of hours they practiced since your last game, and then at your next practice session, you have each girl shoot 10 free throws. Below are the results.Player Hours Practiced Free Throws Made (out of 10)1 5 52 4 53 7 74 8 85 9 86 10 97 1 38 2 49 5 410 6 411 5 312 7 613 9 914 8 915 5 7

4. A research group in PS326 is interested in whether involvement in student life clubs is related to whether or not a student lives on or off campus. The group goes out and asks the first 50 people they see two questions: 1) whether they are a resident or commuter student; and 2) if they currently belong to a BU club or not. Twenty-three students live on campus and 27 are commuters. Below are the results. Live on campus: 18 involved with a club, 5 not involved with a club Live off campus: 10 involved with a club, 17 not involved with a club
a. Write a brief results and discussion section for this data in APA style. Include the effect size statistic in the results sentence if appropriate for this test.
