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.
