What is 2 level factorial design?

Also asked, what is a 2x2 factorial design?

A 2x2 factorial design is a trial design meant to be able to more efficiently test two interventions in one sample. That being said, the two-way ANOVA is a great way of analyzing a 2x2 factorial design, since you will get results on the main effects as well as any interaction between the effects.

One may also ask, what are levels in factorial design? In factorial designs, a factor is a major independent variable. In this example we have two factors: time in instruction and setting. A level is a subdivision of a factor. In this example, time in instruction has two levels and setting has two levels. Sometimes we depict a factorial design with a numbering notation.

Correspondingly, how many conditions are in a 2x2 factorial design?

2x2 = There are two IVS, the first IV has two levels, the second IV has 2 levels. There are a total of 4 conditions, 2x2 = 4.

How do you calculate factorial design?

Essentially, the name of a factorial design depends on the levels of the independent variables. The first number is how many levels (or values) there are of the first factor, and the second number is how many levels there are of the second factor.
