Identify the conditions of a complex design experiment that would be used to examine these variables (i.e., factorial combination).
What will be an ideal response?
A researcher is interested in studying the effectiveness of two different learning strategies (A and B), and whether the effects of the learning strategies differ for easy material compared to difficult material. The researcher has 80 participants available. The dependent variable is percentage correct on tests of the material. The researcher hypothesizes that (1) participants will always have higher test scores for easy compared to difficult material, and (2) learning strategy B will be better than learning strategy A for difficult material, but the strategies will produce little difference in test results for easy material.
