Document Summary

Single factor (one-way: studies one independent variable. Note that the order of the numbers makes no difference: the number of different treatment groups in any factorial design can be determined by multiplying through the number notation, i. e. 3 x 4 = 12 groups. Defined: a research design that uses more than one independent variable. 3 types of factorial designs: between participants, within participants, mixed participants. Between participants factorial designs: a research design in which all independent variables are between participants, each participant is exposed to only one level of each independent variable. Within participants factorial designs: a research design in which all independent variables are within participants, each participant is exposed to all levels of each independent variable. Mixed participants factorial designs: a research design in which not all of the independent variables are one type, one or more independent variables are between participants and one or more independent variables are within participants.
