Document Summary
Behavior is usually influenced by more than one independent variable. Most experimental research designs include more than one independent variable. Experimental designs with more than one independent (manipulated) variable. Factor: refers to each of the manipulated independent variables. As experiments using one independent variable are frequently called one- way designs, experiments with two ivs are called two-way designs, and those with 3 ivs are called three-way designs etc Indicates that because there are two numbers there are two factors, and that each factor has two levels. Two-way design with two levels of each factor is described as 2. 2 x 3 design also has 2 factors, one has 2 levels and the other has 3 levels. 2 x 2 x 2 design has three factors, each has two levels. Total number of conditions can be found through the multiplication of the number levels in each factor: ex. In a 2 x 2 design there are 4 conditions.
