TYPE all your answers on the preformatted file ("SPSS3_answer.docx") and submit it. For calculation of Cohen's d, review the notes and formula sheet. When you decide whether the result is significant (reject Ho) or not significant (fail to reject Ho) by reviewing SPSS output, you need to compare your a (.05 for example) and p value ("Sig" in SPSS). o If p (Sig) a, then the result is not significant. (example: p = .08, a = .05) When you use the one-tailed test, divide p (Sig) value by 2 to get p value for the one-tailed test. (example: p = .08 > p = .04 for one-tailed test) When you type an APA format conclusion (1-c, 2-c, 3-c, & 4-d), o the first sentence should begin with what statistics you use (e.g., independent samples t-test) to test the hypothesis. Make sure to add descriptive statistics (M & SD) in your write-up o make sure that you italicize t, p, and d, but not the numeric values. Please use example write-ups (conclusion; Step IV) that I provided in the lecture summary notes. There are four problems in this assignment. For the problems 1 and 2, you need to use the data that you created for the SPSS assignment 2. Problem 1 - use "Study how" variable Problem 2 - use "Job" and "Mean" variables For the problems 3 and 4, you need to create a new data set. Chapter 9: One sample t test Problem 1. Use the SPSS #2 data file that you created. A national survey reports that college students in general study an average of 3 hours for each quiz. The professor (who collected data on various variables using 40 students in her statistics course) wants to test whether there is a significant difference on average study hours between the students in her statistics course and students in the national survey. Use a two-tailed test with a = .05. a. (1 point) Put the SPSS output (two tables) in the answer file. . (0.5 points) Calculate Cohen's d. Show me all the steps you follow to get d so that I can give you a partial credit when your answer is incorrect. S All these values (M, u, and s) should be found in SPSS output c. (2 points) Make a conclusion with APA format (make sure to italicize statistical symbols), including interpretation of d. Chapter 10: t-test for two independent samples Problem 2. Use the SPSS #2 data file that you created. Is there a significant mean difference between students who have a job and students who do not have a job on the mean scores (average of quiz 1 and quiz 2)? Use a two-tailed test with 1=.05. a. (1 point) Put the SPSS output (two tables) in the answer file.

Chapter 11: t-test for two related samples Problem 3. Using a sample of n = 20 adult women with depression, a researcher would like to examine the effect of exercise on Matched happiness. A sample of 10 pairs (a total of 20 participants) in a large Pair Exercise Control mental health center were selected, and each pair was matched by 15 13 depression level before the treatment, income, level of social 9 support, marital status, and general physical health. The exercise 10 group was instructed to exercise at least 30 minutes per day, three time a week. No exercise instruction was given to the control group 17 10 After 3 months, a Happiness questionnaire was administered to both 15 groups. 10 Is the mean happiness score higher for the exercise group than for the control group? Run two dependent sample t-test using a =.05, a one-tailed test. (1 point) Put the SPSS output (two tables). o. (0.5 points) Calculate d. Show me all the steps you follow to get d so that I can give you a partial credit when your answer is incorrect. d = MD MD and s can be found in SPSS output c.

A researcher is comparing the effectiveness of two methods to remember difficult words. A sample of 24 college students is obtained, and each participant is randomly assigned to one of the two groups. Half of the participants (n = 12) are asked to memorize words using "Saying it Out Loud" method, and the other half (n = 12) receives an instruction to memorize words using "Imagery" method. The researcher measures how many words each participant correctly remembers. Is there a significant mean difference in the number of words correctly remembered between the two groups?
