How do pick-up lines and a person"s scent influence relationship initiation? . Factorial design the most frequently used experimental design for a study that has more than one independent variable. + levels in this case pick up line and scent. Anatomy of a factorial design the number of numbers indicates how many independent variables the design includes. E. g. in a 3 4 factorial design, there are two numbers, so there are two independent variables. E. g. in a 2 2 4 factorial design, there are three numbers, so there are three independent variables. Numbers themselves indicate how many levels or conditions each independent variable has. E. g. in a 3 4 factorial design, the first independent variable has 3 levels, while the second independent variable has 4 levels. However, if one of the independent variables use a within-subject format factorial design becomes a mixed design. Any factorial design that has at least one quasi- independent variable. A variable you cannot manipulate gender.
