Background: Group A the control group uses a website 1. Group B the treatment group uses website B. The expected result is that Group B will have a higher understanding than group A. Hypothesis: The treatment group will show increased levels of understanding. A 1(Strongly Agree) - 7(Strongly disagree) likert survey was used, to measure understanding after the groups used either website 1 or 2.
I know using a two sample t-test will allow me to determine whether a significant difference was present. But how do I determine the direction of the difference through using SPSS? Still new to this. Thanks for the help.
