Common Mistakes to Avoid When Using Between-Subjects Designs:
Not Enough Participants: It's important to have enough people in each group for your study. A good rule is to aim for about 30 people per group. This helps make sure your results are strong and reliable.
Unequal Group Sizes: Try to keep the number of participants in each group the same. If one group has many more people than another, it can mess up your results and make them less trustworthy.
Extra Variables: When you conduct your study, randomly assign participants to different groups. This helps reduce the chance that outside factors will affect your results.
Too Much Variation: If there's a lot of difference among the people in your groups, it can be hard to see the real effects you’re measuring. It’s better to measure groups that are more similar to each other.
