I have little knowledge of statistics and was wondering what tests to use for an evidence-based project (not research, so I am not using a control group) that I am conducting.
What statistical test would I use for pre and post knowledge tests after a student educational intervention?
Also, are numeric test results considered interval data and would I being looking for the difference in means between the pre and post knowledge tests?
I also have pre- and post-confidence scores that have one negative value:
0: do not agree
and two positive values:
1: somewhat agree and 2: strongly agree;
What statistical test would I use for the confidence survey? Would this be ordinal data and again would I be looking for the mean difference between the pre- and post-confidence surveys?
