7. A research study that follows over time groups of individuals who are alike in many ways but differ by a certain characteristic (for example, female nurses who smoke and those who do not smoke) and compares them for a particular outcome

Correct Answer: Correct answer is: (A) Prospective cohort.

Exam Relevance: GRE, MCAT, Epidemiology exams

Difficulty: Moderate

Concept notes: A prospective cohort study follows groups of individuals over time to observe the development of outcomes based on a specific characteristic.

Common Mistakes: A common misunderstanding is confusing a prospective cohort study with a cross-sectional study, which only captures data at a single point in time.

Explanations: A prospective cohort study involves following groups of individuals over time who share many characteristics but differ in a specific variable (such as smoking status). The study then compares these groups to observe the development of a particular outcome, such as the incidence of lung cancer. This method allows researchers to establish temporal relationships and causality, making it a powerful tool in epidemiological research.

Option Analysis:

Option A: This is the correct answer because a prospective cohort study follows groups over time to observe outcomes based on a specific characteristic.
Option B: This is incorrect because a cross-sectional study only captures data at a single point in time and does not follow individuals over time.

8. Which design is least likely to establish causality?

Correct Answer: Correct answer is: (C) Correlational.

Exam Relevance: AP Psychology, GRE Psychology, MCAT

Difficulty: Moderate

Concept notes: Correlational designs are least likely to establish causality because they only measure the relationship between variables without manipulating any of them.

Common Mistakes: A common misunderstanding is that correlation implies causation, but this is incorrect. Correlation only indicates a relationship, not a cause-and-effect relationship.

Explanations: Correlational designs measure the relationship between two or more variables without manipulating any of them. This means that while they can show a relationship or association between variables, they cannot establish causality because they do not control for other potential variables that might influence the relationship. In contrast, experimental and quasi-experimental designs involve manipulation of variables and control for other factors, making them more suitable for establishing causality. Longitudinal designs, while not manipulating variables, can provide insights into temporal relationships, which can be closer to establishing causality than correlational designs.

Option Analysis:

Option A: Experimental designs involve manipulation of variables and random assignment, which can establish causality.
Option B: Quasi-experimental designs involve manipulation of variables but lack random assignment, which can still provide some evidence for causality.
Option C: Correlational designs measure relationships without manipulation, making them least likely to establish causality.
Option D: Longitudinal designs track variables over time, which can provide insights into temporal relationships, but do not manipulate variables.

9. Which of the following research methods is being described?detects naturally occurring relationships, to assess how well one variable predicts another

Correct Answer: Correct answer is: (B) Correlational method.

Exam Relevance: AP Psychology, GRE Psychology, Research Methods in Psychology

Difficulty: Moderate

Concept notes: The correlational method is used to detect naturally occurring relationships between variables and assess how well one variable predicts another.

Common Mistakes: A common misunderstanding is that the correlational method can establish causation, but it only shows the strength and direction of the relationship between variables.

Explanations: The correlational method is designed to detect naturally occurring relationships between variables and assess how well one variable predicts another. This method does not involve manipulating variables or establishing causation, but rather observes and measures the relationship between variables as they naturally occur.

Option Analysis:

Option A: The descriptive method involves observing and recording behaviors or characteristics without manipulating variables, but it does not assess predictive relationships between variables.
Option B: The correlational method is the correct choice because it detects naturally occurring relationships and assesses how well one variable predicts another.
Option C: The experimental method involves manipulating one variable to determine its effect on another, which is not the same as detecting naturally occurring relationships.
Option D: This option is incorrect because the correlational method is a valid research method that fits the description provided.

10. When creating a literature review, which of the following is NOT necessary?

Correct Answer: Correct answer is: (B) Reporting original findings.

Exam Relevance: GRE, PhD Qualifying Exams, Master's Thesis

Difficulty: Moderate

Concept notes: A literature review is a comprehensive summary and analysis of existing research on a topic. It does not include reporting original findings, which are typically presented in research articles or empirical studies.

Common Mistakes: A common misunderstanding is that a literature review should include new data or original research findings. However, the purpose of a literature review is to synthesize and critique existing research, not to present new data.

Explanations: A literature review focuses on summarizing, synthesizing, and critiquing existing research. It does not involve reporting original findings, which are typically presented in research articles or empirical studies. The other options (defining key terms and concepts, analyzing and critiquing sources, and establishing a theoretical or conceptual framework) are all necessary components of a literature review.

Option Analysis:

Option A: Defining key terms and concepts is necessary to ensure clarity and consistency in the review.
Option B: Reporting original findings is not necessary in a literature review, as it focuses on existing research.
