Hi...
I need some help with the basics...
What is meant by an interaction in an experiment?
And... Can you please tell me a link where I can find examples of experiments that have between-subjects, within-subjects and mixed designs.

Thank you very much, people!

Erida,

As an example, let's say we have an experiment with two factors, A and B, each at two levels - so this would be a 2x2 design.

An interaction between factors A and B would mean that the effect of factor A would depend on the level of B, or vice versa-
the effect of factor B would depend on the level of A.
