Question

​Michelle is conducting an experiment in which she is evaluating the effects of reward magnitude and reward immediacy on classroom behavior. She has two levels of reward (Low and High) and two levels of immediacy (Daily and Weekly) with four groups: Low-Daily, Low-Weekly, High-Daily, and High-Weekly. Michelle's design is best described as ____.

Answer 1

Fully crossed design

Explanation:

The factorial research design is also called a fully crossed design. This design consists of all possible combinations of their level across all the levels of the research design. It is also called a fully crossed design. This type of research allows the valuable variables cross combination and also shows the effect of all variables. In the experiment method, all variables have only two-level and four treatment combination in all that is called as 2*2 factorial design. In some factorial design, some unwanted or fractional levels can be omitted to make a useful combination.
