PUBH 6033—Week 2 Assignment 1

Hands on SPSS!

(Rubric included)

Instructions

For this assignment, review this week’s Learning Resources, and then create and analyze frequency distributions and summary statistics of data provided as a Microsoft Excel file. Import the data into SPSS. Then run frequency distribution graphs and tables and calculate summary statistics in SPSS as instructed below. Note: It is recommended that you save the SPSS data file, as you will use the same file for a Week 7 Application Assignment. Type your answers to all questions and paste all required output directly into the worksheet at the end of this document.

Submit this Application Assignment by Day 7.

Research Scenario

A study was conducted to determine if a walking plus strength training exercise program results in a significantly greater increase in aerobic capacity as compared to a walking only exercise program.  Participants are randomly selected and then randomly assigned to one of the exercise groups.  Participants’ aerobic endurance was assessed at the beginning of the study and, again, after 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 of in Step 11.

Step 1: Review this week’s Learning Resources.

Step 2: Import the Microsoft Excel data file provided in this week’s learning resources into SPSS.

Step 3: Run and save the Codebook for your SPSS data file.

Step 4: Create an ungrouped frequency distribution table for each of the following:

AGE, SEX, EXERCISE, and CHNG_ENDUR.

Step 5: Run descriptive/summary statistics (mean, median, mode, standard deviation, and range) for both exercise types combined for AGE and CHNG_ENDUR.

Step 6: SPLIT the data file by exercise type (EXERCISE).

Step 7: Create a line graph that illustrates CHNG_ENDUR for each exercise type separately.

Step 8: Create pie charts for SEX for each exercise type group.

Step 9: Run descriptive/summary statistics (mean, median, mode, standard deviation, and

range) for each exercise type separately for AGE and CHNG_ENDUR.

Step 10: Review all of your SPSS output and answer each of the following questions:

Step 11: Paste all required output below.
