Questions: QUESTION 2 What type of study can be described as a "study of studies"? a. meta-analysis b. experiment c. correlational d. case QUESTION 3 According to the text, how do hypotheses relate to theories?

The answer is the first one (or A): meta-analysis.

Explanation for each option: a. Meta-analysis: This is the correct answer. A meta-analysis is a statistical technique that combines the results of multiple scientific studies. It is often referred to as a "study of studies" because it synthesizes data from various research papers to draw a more comprehensive conclusion.

b. Experiment: This is incorrect. An experiment is a research method where the investigator manipulates one or more variables to determine their effect on a dependent variable. It is not a study of studies but rather a single study designed to test a hypothesis.

c. Correlational: This is incorrect. A correlational study examines the relationship between two or more variables to determine if they are associated. It does not combine multiple studies but rather looks at data within a single study.

d. Case: This is incorrect. A case study is an in-depth analysis of a single individual, group, event, or situation. It does not involve combining multiple studies but focuses on detailed examination within a single context.

Summary: The type of study described as a "study of studies" is a meta-analysis. This method combines results from multiple studies to provide a more robust conclusion.
