Short Answer

Apply the movie-choice example from the text to create a hypothetical scenario representing a 2×22 \times 2 factorial design where a student's choice to study depends on both the difficulty of the subject (easy vs. hard) and the location (library vs. home). Describe what the interaction effect would look like in this scenario.

Question: Apply the movie-choice example from the text to create a hypothetical scenario representing a 2×22 \times 2 factorial design where a student's choice to study depends on both the difficulty of the subject (easy vs. hard) and the location (library vs. home). Describe what the interaction effect would look like in this scenario.

Sample answer: In this scenario, a student's decision to study depends on the combination of subject difficulty and location. An interaction effect occurs if the student prefers to study at the library only when the subject is hard, but prefers to study at home when the subject is easy.

Key points:

  • Apply the concept of interaction to a new factorial scenario with two independent variables: subject difficulty and location.
  • State that the decision to study is determined by the combination of both factors.
  • Describe a specific outcome where the effect of the location depends on the difficulty of the subject.

Rubric: The answer must describe a study decision that depends on the combination of both factors (subject difficulty and location), showing how the effect of one factor changes depending on the level of the other factor.
