Question

In an experiment examining the effects of stress on decision making, researchers use two independent variables with two levels each. The first independent variable is temperature of the room (65 degrees and 95 degrees) and the second is noise in the room (present or absent). Researchers randomly assign participants to one of the two temperature conditions and then have the participants perform decision-making tasks in both conditions of the noise variable (present and absent). The researchers allow subjects to rest in between exposure to the noise variable and use counterbalancing of the noise conditions. This experiment uses a(n) _____ design, since subjects are randomly assigned to one independent variable, but exposed to all conditions of the second independent variable.

Answer 1

Answer:Mixed factorial design

Explanation:

Mixed factorial design is a design that involve the use of two or more independent variable where one of the independent variable is between group and the other is within subject independent variable.

Temperature is the independent variable between the group and noise is the independent variable that is exposed to within the subject.

It is mixed because it has many factors relating together.
