MULTIPLE CHOICE. 10 POINTS (5 EACH) Conduct the following analyses using the provided dataset and select the choice that best answers the question. Some analyses may require the use of Select If, Split File, or both. 1. Test the hypothesis that people who work more hours are harder working, and therefore are also better students. Find the Pearson's correlation between WorkHrspw and GPA for people who have jobs. Which of the following is the correct test result for this correlation? a. r(51) = .92, p < .05 b. r(98) = .05, p > .05 c. r(51) = .02, p > .05 d. r(98) = .65, p < .05 Your answer: 2. A researcher uses an independent samples t test to test the hypothesis that people who don't play video games have a higher mean overall GPA than people who do play video games. Which of the following is the correct APA style write up for the results? a. There was no significant difference in mean GPA between people who don't play video games (M = 2.52, SD = .83) and people who do play video games (M = 2.11, SD = .68), t(98) = -2.56, p > .05, d = .52 b. The mean GPA of people who don't play video games (M = 2.52, SD = .83) was significantly higher than that of people who do play video games (M = 2.11, SD = .68), t(98) = -2.56, p < .05, d = .52. c. There was no significant difference in mean GPA between people who don't play video games and people who do play video games, t(98) = -2.56, p > .05, d = .52. d. The mean GPA of people who don't play video games (M = 2.52, SD = .83) was significantly higher than that of people who do play video games (M = 2.11, SD = .68), t(98) = -2.56, p < .05, d = .52. Your answer: PART 2. APA STYLE WRITE UPS. 40 POINTS (10 EACH). Present full APA style write ups for the following two analyses. Some analyses may require the use of Select If, Split File, or both. Grading criteria: 5 points for correct statistics and test results. 5 points for correct APA style. 1. Test the hypothesis that for people who do work and do play video games, there is a significant negative correlation between GPA and number of hours spent playing video games per week (VideoGameHrspw). Enter APA Style Write Up Below 2. Using an independent samples t test, test the hypothesis that people who work full time have significantly lower mean overall GPAs than people who work part time. Enter APA Style Write Up Below 3. The researcher believes that academic performance is generally stable, and that it should not vary much from semester to semester. Using a repeated-measures t test, test the hypothesis that there will be no significant difference in GPA between spring 2015 and fall 2015 for people with an overall GPA greater than 2.5. Enter APA Style Write Up Below 4. Using a between groups (one-way) ANOVA, test the hypothesis that people who don't have jobs have less anxiety than people who work part time, and that people who work part time have less anxiety than people who work full time. (You must report follow-up pairwise comparisons if the omnibus ANOVA is significant. Use Tukey's HSD.) Enter APA Style Write Up Below
