Understanding Research Designs

What is the primary difference between a between-subject design and a within-subject design?

• Within-subject design involves different participants in each condition.

• Between-subject design involves the same participants in all conditions.

• Within-subject design involves participants being assigned to only one condition.

• Between-subject design involves different participants in each condition.

In a within-subject design, what is a key advantage?

• It requires fewer participants.

• It avoids any order effects.

• It eliminates all external variables.

• It is easier to analyze.

Which of the following is an example of a within-subject design?

• Comparing stress levels of different people before and after a vacation.

• Testing the same group of people with two different types of baseball bats.

• Assigning different diets to different groups of people.

• Surveying different groups of people about their income.

What is a characteristic of a between-subject design?

• It requires fewer participants than a within-subject design.

• Participants experience all levels of the independent variable.

• Participants are randomly assigned to only one condition.

• It is always more accurate than a within-subject design.

In the context of ANOVA, what does a between-subject factor imply?

• The same participants are measured multiple times.

• All participants are exposed to all conditions.

• It involves only one group of participants.

• Different participants are exposed to different conditions.

What is a mixed model ANOVA used for?

• Analyzing data with only one independent variable.

• Combining both between-subject and within-subject factors.

• Comparing more than two groups with repeated measures.

• Testing the effect of one factor at a single time point.

When would you use a mixed model ANOVA?

• When you have no repeated measures.

• When there is only one independent variable.

• When you have both between-subject and within-subject factors.

• When you want to compare two groups only.

Which hypothesis test is appropriate for a between-subject design?

• Independent samples T-Test

• Paired samples T-Test

• Chi-square test

• Repeated measures ANOVA

What tool can help you select the right hypothesis test based on your data?

• Excel

• SPSS

• R Studio

• data.net

In the data.net demonstration, what test is calculated when all variables are selected?

• Mixed model ANOVA

• Repeated measures ANOVA

• One-way ANOVA

• Paired samples T-Test
