Analysis of 2 groups?
 

I am trying to use the Analysis ToolPak add in to crunch some research
numbers. The research is comparing two groups after two different testing
sessions on a 7 point likert scale. Should I use an Anova or Paired T-Test?
Furthermore, any ideas on how to put the data in? I have done both but they
do not look correct. Any thoughts are appreciated.

You can do an ANOVA with Tools Data Analysis Regression.

Also, check these out:
