REVISED In-Class Assignment Directions: Running Your Quantitative Data

This is your in-class assignment for Wednesday, March 31. Access the SPSS file on ULearn. You will complete to the best of your ability and turn in

How to Run Your Quantitative Data

1. Open up the data file. It is located on the main/front page of ULearn.

2. Save the SAV data file as YOURNAMEGOESHERE_CLASS_TINDALL.sav

3. Run frequencies with means and standard deviations on all of your data.*

4. Save your output file (GROUPNAME_CLASS_TINDALL, FREQUENCIES.spv).

5. Save the SPV output file. Print the output file.

6. Run crosstabs on the appropriate variables within your data. **

8. Save the SPV output file.

9. If there is time, run correlations on the appropriate variables.***

10. Save the SPV output file.

11. Open Microsoft Word to create a table -- you are going to take your SPSS output to create a nice looking table in MS Word.

12. Use the output from step 3, 8, and 10 to populate tables. Describe the sample where you write a sentence telling the number and percent of one gender. Make sure you bold the numbers you talk about in the table. For example you might say "A majority of the respondents were female (60%; n = 6). DO THIS FOR ALL OF YOUR OUTPUT VARIABLES. Give the table a descriptive name that explains what the data in the table talks about.

13. Send your documents to me via e-mail.


* How to Run Frequencies
To view a frequency distribution, go to the top of the screen and click on the Analyze tab.

Analyze > Descriptive Statistics > Frequencies

This will open up a window. In the window, select the variables you want to use for the distribution by double clicking them.
Then hit OK and SPSS will start running a frequency table.

** How to Run Crosstabs


RUN: CLICK ON ANALYZE>DESCRIPTIVE STATISTICS>CROSSTABS
MOVE ONE VARIABLE TO THE ROWS AREA AND ONE VARIABLE TO THE COLUMN VARIABLE (DOES NOT MATTER WHICH IS WHICH)
CLICK ON STATISTICS ON THE BOTTOM AND MAKE SURE THE CHI-SQUARE BOX IS CHECKED THEN CLICK CONTINUE
CLICK ON CELLS ON THE BOTTOM AND MAKE SURE THE ALL THE COUNT BOXES ARE CHECKED AND ALL THE PERCENTAGE BOXES ARE CHECKED THEN CLICK CONTINUE.
CLICK ON OK TO RUN THE CROSSTAB ANALYSIS.

CROSSTABS ARE FOR NOMINALLY SCALED VARIABLES, I.E. CATEGORICAL. NUMBER OF CATEGORIES IN THE TWO VARIABLES BEING TABBED SHOULD NOT HAVE A PRODUCT GREATER THAN 16, I.E. VARIBLE ONE HAS 4 CATEGORIES, VARIABLE TWO HAS 4 CATEGORIES: 4x4 = 16. (ok).
MEASURES ASSOCIATIONS, NULL HYPOTHESIS: NO RELATIONSHIPS BETWEEN THE TWO VARIABLES BEING TABBED


***CORRELATIONS:
YOU CAN ONLY RUN CORRELATIONS ON INTERVAL OR RATIO DATA
NULL HYPOTHESIS: NO RELATIONSHIPS
ONLY CORRELATIONS WITH P-VALUES LESS THAN .10 ARE CONSIDERED SIGNIFICANT, I.E. REJECT THE NULL HYPOTHESIS.
CLICK ON ANALYZE>CORRELATE>BIVARIATE
MOVE ALL VARIBLES YOU WANT TO CORRELATE INTO THE VARIABLES BOX
CLICK OK
