Figure:
A researcher examined whether interrogators who expect a suspect to be guilty,rather than innocent,use more persuasive interrogation techniques.The researcher created a laboratory situation in which students (the "suspects")were randomly assigned to actually commit a crime or not commit a crime by following a set of instructions given to them.Student interrogators then interviewed a suspect;they were randomly assigned to conditions that led them to believe the suspect was guilty or innocent of the crime.Observers rated the effort used by interrogators to obtain a confession using a 1-10 rating scale (higher scores indicate greater effort).
Suppose the researcher observed the following means for each group:
-The design on this experiment would be described as a
A)2 × 2.
B)2 ×10.
C)2 × 2 × 2.
D)2 × 2 × 10.

The design is a 2 × 2 factorial design, which means there are two independent variables, each with two levels.
