PSY 301 Chapter Notes - Chapter 12: Factorial Experiment, Cold Food Festival, Weighted Arithmetic Mean
Document Summary
Experiments with two independent variables can show interactions. Interaction effect: whether the effect of the original independent variable depends on the level of another independent variable. Such as whether age of driver depends on how cell phone use affects driving ability. When asked if you like hot or cold food it depends on two variables: temperature of food and what food you are judging. Crossover interactions can be described with the phrase it depends , there is a difference of differences. Spreading interactions can be described using the phrase. Factorial design: there are two or more independent variables when testing for an interaction. Study each possible combination of the independent variable. The overlay process creates unique conditions, or cells, depending on which levels of which ivs are included. Participant variable: a non-manipulated variable,where the levels are selected (measured) Test whether an independent variable affects different kinds of people, or people in different situations, in the same way.
