Experimental Designs in Research

Play an AI-generated podcast conversation about this lesson

In a within-subjects experimental design, what happens?

Subjects are matched based on their characteristics

Different groups of subjects experience different treatments

The same subjects go through all treatments (correct)

Subjects are assigned to different conditions to minimize variation

What is the purpose of a control condition in an experiment?

To create different treatment groups

To provide valuable information about interactions

To manipulate independent variables

To establish a baseline for comparison (correct)

What is the distinction between between-subjects and within-subjects designs?

Within-subjects designs involve randomization

Between-subjects designs have the same subjects for all treatments

Within-subjects designs involve the same subjects for all treatments (correct)

Between-subjects designs are more efficient
