Quiz on Alternatives to Experimentation

What is a key feature of quasi-experimental designs?

• Random assignment of participants

• Manipulation of independent variables

• Complete control over variables

• Use of control groups when possible

Which of the following is an example of a quasi-experimental design?

• Meta-analysis

• Double-blind study

• Non-equivalent groups design

• Randomized controlled trial

What does correlational research primarily explore?

• The effects of interventions

• The strength and direction of relationships

• Random assignment of participants

• Causal relationships between variables

What is a limitation of quasi-experimental designs?

• They are less practical in real-world settings

• They cannot provide evidence of change over time

• They require random assignment

• They have threats to internal validity

Which tool is commonly used in correlational research?

• Regression analysis

• ANOVA

• Pearson's r

• T-test

What is the main difference between quasi-experimental and correlational designs?

• Correlational designs can establish causality

• Quasi-experimental designs have random assignment

• Correlational designs use control groups

• Quasi-experimental designs manipulate variables

What does a scatterplot represent?

• The relationship between two variables

• The distribution of a single variable

• The results of a randomized trial

• The effects of an intervention

What is a strength of correlational research?

• It can handle large datasets

• It establishes causality

• It uses random assignment

• It allows for manipulation of variables

What is the third-variable problem?

• The random assignment of participants

• The lack of control over variables

• The inability to measure variables accurately

• A third factor that influences both variables

In a pretest-posttest design, what is measured?

• Different groups at the same time

• The same group before and after an intervention

• Only the post-intervention results
