Document Summary

Factorial design involves any study with more than one iv. It is described with a numbering system that simultaneously identifies the number of iv and the number of levels in each variable. The conditions to be tested on compared can be determined by looking at all of the combinations of different levels of each iv through a factorial matrix. The main effect is used to describe the overall effect of a given iv equally the number of possible main effects or equal the number of iv. It is the mean for one particular iv level involving the combination of all the data for each of the levels of that factor. The interaction effect occurs when the effect of one iv depends upon the level of the other iv. Ceiling effect: occurs when scores in 2 or more conditions are near the maximum.
