					Data Analysis for Project 2:

The data file is in a folder in the Fall 2005 folder on the T: drive labeled "Project 2 data
file and syntax." You should copy this file to you O: drive before doing anything with it
(including opening it).

You have handouts on how to get all of this. If you don’t have copies see
https://netfiles.uiuc.edu/smith5/www/teaching.html for copies of all
instructions.

   **** USE “PASTE” AND SAVE YOUR OUTPUT AND
 SYNTAX AS YOU GO ALONG SO WHEN SPSS CRASHES
               YOU WON’T BE SAD***
Descriptive Statistics

Number of Participants (N) ____________________________

Gender: % Men ______ % Women ______ N Men _____ N Women ______

Age: Mean ________ SD _________ Range _____________

Ethnicity: % Each _______________________ N Each _________________________

Reliabilities

Syntax files for computation are on the T drive, copy to your O drive

Reliability for 8 factor measure of C _______

Reliability for 10 Processes of change (POC) ______

FOR THE C8, YOU MUST RUN THE REVERSE CODE COMMAND BEFORE
CREATING THE SCALES.

For the C8, items from some scales have already been dropped to improve reliability (this
is noted in the syntax), but you should note which scales showed less than ideal
reliabilities.

Manipulation check ANOVA

GLTEQ by stage ANOVA done on 10/31
Correlations

1. Correlate the C8 scales and the POC scales.

Again, refer to the handout about correlations to run these analyses. To aid in these
analyses, it is useful for to know how to use the 'with' joiner. After you've gone from
Analyze-->Correlate-->Bivariate... and put the C8 and POC variables in the right
window, click Paste. This will put the syntax for the correlation in an open Syntax file or
a new Syntax file. Then put the word “with” between the last C8 variable and the first
POC variable. Then you can execute the command and get a more manageable table of
correlations.

2. Correlate the C8 and POC with GLTEQscore1 (use the “with” joiner here too).

ANOVA

Run ANOVA for the C8 by TTM stage. So TTM is the IV as before with C8 as DVs just
as you did on 10/31 but with Conscientiousness instead of exercise behavior.

Prediction

Correlate C8 with GLTEQscore2 (you can use the “with” joiner here too).


**Save all of this as you will write it all up with my help over the next week or so.
