Research Methodology: Analysis of Results
Reported as the difference between mean scores of the Pre-session (Experimental) Group and the No Pre-session (Control) Group.
Raw scores based on a 1 to 7 scale. A low raw score 1 indicated a negative response. A high raw score 7 indicated a positive response.
Presumably, students in both groups would score higher on post-tests as a result of the library instruction class.
