Dear Colleagues,
I'd be thankful if you help me with my analysis.
I want to study the impacts of modality of listening comprehension tests (audio vs. video) and the presence of some pictorial aids with three levels (1. no pictorial aid, 2. simultaneous pictorial aid when doing the test and, 3. pictorial aid with some time laps) on the performance of the subjects on the listening test.
I think I need to use two-way ANOVA, right?
I have run two separate one-way ANOVA's within the three levels of Audio Group and Video Group. Is this wrong?
What can I exactly learn about my variables by running two-way ANOVA?
What interactions can exactly be there?
I already have the following descriptive stats.
Regards
Humphrey
