which statistics test do I need to follow ?

Question

This suggests that how one learns (e.g. literally-verbal lecture, witnessed demonstration, engaged activity) and learned outcomes are linked.

In an experimental test (note the italics for emphasis) of this idea, researchers want to know whether differences in mode of learning are causally related to depth of learning (e.g., recall vs. application) among college students.

Be creative and think of a research question that tests the validity of this claim using a research design to determine cause and effect.

Answer 1

Paired t-test?  Dependent pairs?  Not sure of the language you are using.  I am assuming that you are using the same people and exposing them to different teaching styles and measuring the outcome of their learning?
