Youtube Links about SPSS Analysis

For the first three sections of your Results section (i.e., demographics, dependent variable, independent variables and covariates):

Frequencies: http://www.youtube.com/watch?v=outMas3NrQ8&feature=related (scroll ahead to ~ minute 1:25)

Descriptives: http://www.youtube.com/watch?v=0T-6bcS0tss&feature=mfu_in_order&list=UL


For the fourth section of your Results section (i.e., significance tests):

The type of tests you choose to run to test for significance will depend on the type of variables you are using, continuous or categorical. Here's a video about variable types: http://www.youtube.com/watch?v=CNW9txOMYAg. 

(1) Independent samples t-test: http://www.youtube.com/watch?v=vtkW1il7kRc&feature=BFa&list=ULrM-yPWI6zgo&lf=mfu_in_order

(2) Correlation: http://www.youtube.com/watch?v=cNrnSEWKJgg&feature=related and also http://www.youtube.com/watch?v=Bl62NKXAe8w&feature=BFa&list=ULkMpty0exwHo&lf=mfu_in_order 

Here also is a video on how to interpret the correlation coefficient (significance, sign, and size!): http://www.youtube.com/watch?v=jf-SIOFUuEo.

(3) Crosstab w/chi square: http://www.youtube.com/watch?v=Ahs8jS5mJKk

Specifying missing values in SPSS: http://www.youtube.com/watch?v=wfwUC0XSnUA This is particularly relevant for the students using existing data. If the data's principal investigator(s) didn't already designate values as discrete missing values, you'll need to do this.
