Outline:-- why we do them-- language-- Main Effects and Interactions -- Definitions -- Graphs -- Math (ANOVA) approach -- When the Math and Graph do not agree. Factorial Designs are those that involve more than one factor (IV). In this course we will only deal with 2 factors at a time -- what are called 2-way designs.

In a factorial design each IV will have it’s own main effect. A design with p such generators is a 1/(l p)=l-p fraction of the full factorial design. For example, a 2 5 − 2 design is 1/4 of a two level, five factor factorial design. Rather than the 32 runs that would be required for the full 2 5 factorial experiment, this experiment requires only eight runs. Useful fractional factorial designs for up to 10 factors are summarized here: There are very useful summaries of two-level fractional factorial designs for up to 11 factors, originally published in the book Statistics for Experimenters by G.E.P.

They can test these theories using factorial designs, and manipulating X or Y as a second independent variable. In a factorial design each IV will have it’s own main effect.

In statistics, a full factorial experiment is an experiment whose design consists of two or more factors, each with discrete possible values or "levels", and whose experimental units take on all possible combinations of these levels across all such factors.

Is this an IV X PV design? If so, identify the participant variable(s).
