PUBH 6033—Week 7 Assignment 1 Comparing two means: When drink drove a Student to staTsTcs (Rubric included) InstrucTons For this assignment, you review this week’s Learning Resources and then perform a two-sample independent t -test and an ANOVA related to the dataset that was uTlized in the week 2 SPSS applicaTon assignment. Import the data into SPSS; or, if you correctly saved the data ±le in week 2, you may open and use that saved ±le to complete this assignment. ²ype your answers to all quesTons directly into the worksheet, and paste the required output at the end of this document. Submit this ApplicaTon Assignment by Day 7. --------------------------------------------------------------------------------------------------------------------- Research Scenario A study was conducted to determine if a walking plus strength training exercise program results in a signi±cantly greater increase in aerobic capacity as compared to a walking only exercise program. ParTcipants are randomly selected and then randomly assigned to one of the exercise groups. ParTcipants’ aerobic endurance was assessed at the beginning of the study and, again, a³er 6-months of exercise. Coding for study variables: AGE—age in years SEX—1 =male, 2=female EXERCISE—1= walking and strength training; 2 = walking; CHNG_ENDUR—change in maximal oxygen uptake (liters per minute) from pre-test to post-test --------------------------------------------------------------------------------------------------------------------- Note : Save all of your SPSS output. You will paste copies in steps 7-9, below. Step 1: Review this week’s Learning Resources. Step 2: Import the Microso³ Excel data ±le provided in this week’s learning resources into SPSS (or open saved ±le from week 2 applicaTon assignment). Step 3: Run and save the Codebook for your SPSS data ±le Step 4: Conduct an independent samples t-test to determine if there is a di´erence between the exercise type 1 and 2 in terms of changes in maximal oxygen uptake. Note that the

independent variable is EXERCISE, and the dependent variable is CHNG_ENDUR. For this analysis, choose a two-tailed test of signi±cance. Step 5: Conduct a between-subjects ANOVA to determine if there is a di²erence between sex (males vs. females) and CHNG_ENDUR. Note that the independent variable is SEX, and the dependent variable is CHNG_ENDUR. For this analysis, choose a two-tailed test of signi±cance. Step 6: Review your SPSS output and answer each of the following quesTons: QUESTION type answers below Score (to be entered by instructor) From the independent samples t-test output: 1. What is the mean CHNG_ENDUR for group 1? ________________ ____ / 3 points 2. What is the CHNG_ ENDUR standard deviaTon for group 1? ________________ ____ / 3 points 3. What is the mean CHNG_ENDUR for group 2? ________________ ____ / 3 points 4. What is the CHNG_ ENDUR standard deviaTon for group 2? ________________ ____ / 3 points 5. What is the value of the t-staTsTc (equal variances assumed)? ________________ ____ / 3 points 6. What is the probability that the obtained t- staTsTc was simply due to chance as opposed to actual exercise type di²erences [see “Sig (two-tailed)” on output]? ________________ ____ / 3 points 7. Are the results staTsTcally signi±cant at alpha = 0.05 (yes or no)? ________________ ____ / 3 points 8. Based on the results, do you reject or fail to reject the null hypothesis? ________________ ____ / 3 points From the ANOVA output: 9. What is the mean CHNG_ENDUR for males? ________________ ____ / 3 points 10. What is the CHNG_ENDUR standard deviaTon for males? ________________ ____ / 3 points 11. What is the mean CHNG_ENDUR for females? ________________ ____ / 3 points 12. What is the CHNG_ENDUR standard deviaTon for females? ________________ ____ / 3 points 13. What is the calculated F-value? ________________ ____ / 3 points 14. What is the probability (noted as “Sig” on output) that the obtained F-value was simply due to chance as opposed to actual gender ________________ ____ / 3 points
