# Spss analyze frequency distribution and summary statistics

DUE 9/8/17 7P.M EST KNOW BIOSTATS

ATTACHING THE ACTUAL HW SHEET  and also attaching the ASSIGN DATA

You will 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. Type your answers to all questions and paste all required output directly into the worksheet at the end of this document.

———————————————————————————————————————

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:

QUESTION

Score (to be   entered by instructor)

1. How many participants were   female?

/ 1 point

2. How many participants were aged 40–49 years?

/ 1 points

3. What percent of participants were 39 years old or younger?

/ 1 points

4. How many participants had 5 liter/min. increase in their maximal   oxygen uptake?

/ 1 points

5. How many participants had 7 liter/min. increase in their   maximal oxygen uptake?

/ 1 points

For exercise types 1 and 2 combined:

6. What is the mean for AGE?

/ 1 points

7. What is the median for   AGE?

/ 1 points

8. What is the standard   deviation for AGE?

/ 1 points

9. What is the mean for   CHANGE_ENDUR?

/ 1points

10. What is the median for CHANGE_ ENDUR?

/ 1 points

11. What is the range for CHANGE_ ENDUR?

/ 1 points

12. What is the standard deviation for CHANGE_ ENDUR?

For exercise type 1 (walking and strength   training):

13. What is the mean for   CHANGE_ ENDUR?

/ 1 points

14. What is the median for   CHANGE_ ENDUR?

/ 1 points

15. What is the standard   deviation for CHANGE_ ENDUR?

/ 1 points

For exercise type 2 (walking only):

16. What is the mean for   CHANGE_ ENDUR?

/ 1 points

17. What is the median for   CHANGE_ ENDUR?

/1 points

18. What is the standard   deviation for CHANGE_ ENDUR?

/1 points
