PUBH 6033 :Coding for Study Variables - Change in Maximal Oxygen Uptake - Health Assignment Help

Assignment Task :

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

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.  

QUESTION

• How many participants were female?
• How many participants were aged 40–49 years?
• What percent of participants were 39 years old or younger?
