Document Summary
Research methods textbook notes experiments with more than one independent variable. E. g. testing to see if hands free cell phones causes people to drive badly, but testing younger and older people. Interaction effect asking about the effect of an additional iv: e. g. whether the effect of the original iv (cell phone use) depends on the level of another iv (drivers age) E. g. when you don"t say anything, despite having a treat or not, the dog won"t sit either way: large difference when there is a large difference between the conditions. E. g. when you have the treat and say sit, vs. when you have the treat and don"t, the dog only sits when you have the treat and say sit. Factorial designs study two iv: factorial design there are two or more iv"s. In the most common factorial design, researchers cross the two iv"s they study each possible combination of the iv"s. E. g. the driving example as talked about previously.
