Option A: Correct. The unit of analysis is the entity being studied, which in this case is individual customers.
Option B: Incorrect. The relevant variable refers to the specific factors or characteristics being measured, not the entity being studied.
Option C: Incorrect. The decision problem is the issue or question that the research aims to address, not the entity being studied.
Option D: Incorrect. The research problem is the broader issue or gap in knowledge that the research aims to investigate, not the entity being studied.

4. What research design aims to determine a cause from already existing effects?

Correct Answer: Correct answer is: (D) Ex Post Facto.

Exam Relevance: Research Methods, Psychology Exams, Social Science Exams

Difficulty: Moderate

Concept notes: Ex Post Facto research design is used to determine a cause from already existing effects. This design is retrospective and examines existing data to infer causality.

Common Mistakes: A common misunderstanding is that Ex Post Facto research is the same as experimental research, which involves manipulating variables to establish causality. Ex Post Facto research, however, relies on existing data and cannot manipulate variables.

Explanations: Ex Post Facto research design aims to determine a cause from already existing effects by analyzing data that has already been collected. This design is retrospective and does not involve manipulating variables, unlike experimental research. It is used to infer causality based on existing data, making it suitable for situations where manipulating variables is not feasible or ethical.

Option Analysis:

Option A: Descriptive Research Design is used to describe characteristics of a population or phenomenon, not to determine causality.
Option B: Correlational Research Design examines the relationship between variables but does not establish causality.
Option C: Quasi-Experimental Research involves manipulating variables but lacks random assignment, making it less rigorous than true experimental designs.
Option D: Ex Post Facto research design is the correct choice as it aims to determine causality from existing effects.

5. These are set so that your goals do not become impossibly large to complete.

Correct Answer: Correct answer is: (B) Delimitations.

Concept notes: Delimitations in research design refer to the limitations or boundaries set to make the research more manageable and achievable. They help ensure that the goals of the research are not overly ambitious and can be realistically completed.

Common Mistakes: A common misunderstanding is confusing delimitations with scope. While scope defines the breadth and depth of the research, delimitations are the specific limitations that make the research feasible.

Explanations: Delimitations are set to ensure that the research goals are not overly ambitious and can be realistically completed. They help in defining the boundaries of the study, making it more manageable and achievable. This aligns with the statement that these are set so that goals do not become impossibly large to complete.

Option Analysis:

Option A: Scope refers to the breadth and depth of the research, not the limitations that make it manageable.
Option B: Delimitations are the specific limitations that make the research feasible and manageable.
Option C: While both scope and delimitations are important, the question specifically refers to making goals manageable, which is the role of delimitations.
Option D: This option is incorrect as delimitations are the correct answer.

6. For a study on anxiety among first-time mothers, which criterion aligns with the inclusion list shown?

Correct Answer: Correct answer is: (D) Participants must be first-time mothers.

Exam Relevance: GRE, MCAT, Psychology exams

Difficulty: Easy

Concept notes: Inclusion criteria in research design specify the characteristics that participants must have to be included in the study. For a study on anxiety among first-time mothers, the inclusion criterion would be that participants must be first-time mothers.

Common Mistakes: A common misunderstanding is to confuse the inclusion criteria with exclusion criteria, which specify characteristics that would disqualify participants from the study.

Explanations: The study focuses on anxiety among first-time mothers, so the inclusion criterion must align with this focus. Therefore, participants must be first-time mothers to be included in the study.

Option Analysis:

Option A: This option is incorrect because the study is focused on first-time mothers, not those with multiple prior births.
Option B: This option is incorrect because hospital administrators are not the target population for studying anxiety among first-time mothers.
Option C: This option is incorrect because the study is focused on mothers, not fathers of newborns.
Option D: This option is correct because the study is specifically about anxiety among first-time mothers, so participants must be first-time mothers.

7. There is no control for participant variables. For example, participants in one group may be naturally better at the task given.

Correct Answer: Correct answer is: (A) Weakness of Independent Measures Design.

Exam Relevance: AP Psychology, IB Psychology, Undergraduate Psychology

Difficulty: Moderate

Concept notes: In independent measures design, different participants are used in each condition. This can lead to variability due to differences between participants, which can affect the results.

Common Mistakes: A common misunderstanding is that participant variables can be controlled through random assignment, but this does not eliminate inherent differences between participants.

Explanations: The independent measures design involves using different participants for each condition. This means that any differences between the groups could be due to individual differences among participants rather than the experimental manipulation. For example, if one group naturally performs better on a task, this could confound the results. This lack of control over participant variables is a recognized weakness of the independent measures design.

Option Analysis:

Option A: Correct. The independent measures design does not control for participant variables, which can introduce variability into the results.
Option B: Incorrect. Repeated measures design involves the same participants in all conditions, which can control for participant variables but introduces other issues like order effects.
Option C: Incorrect. Matched-pair design attempts to control for participant variables by matching participants across conditions, which is not a weakness.
Option D: Incorrect. The statement accurately describes a weakness of the independent measures design.

8. Methodology allows other researchers to replicate the study.

Correct Answer: Correct answer is: (A) TRUE.

Exam Relevance: GRE, GMAT, Research Methods Exams

Difficulty: Easy

Concept notes: Methodology in research design refers to the detailed procedures and techniques used to conduct a study. It is crucial for ensuring that other researchers can replicate the study to verify results and build upon the findings.

Common Mistakes: A common misunderstanding is that methodology only refers to the theoretical framework of a study, but it also includes the specific steps and procedures used in data collection and analysis.

Explanations: Methodology in research design is detailed and comprehensive, allowing other researchers to follow the same steps and procedures to replicate the study. This ensures the reliability and validity of the research findings.

Option Analysis:

Option A: Correct. Methodology allows other researchers to replicate the study.
Option B: Incorrect. Methodology does allow replication.
Option C: Incorrect. Not all options can be true simultaneously.
Option D: Incorrect. At least one option is true.

9. The extent to which a study's results are the product of the manipulation of the independent variable (and not extraneous variables).

Correct Answer: Correct answer is: (C) Internal validity.

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

Difficulty: Moderate

Concept notes: Internal validity refers to the extent to which a study's results can be attributed to the manipulation of the independent variable rather than other extraneous variables.

Common Mistakes: A common misunderstanding is confusing internal validity with external validity, which refers to the generalizability of the study's findings to other settings, populations, or times.

Explanations: Internal validity is concerned with the causal relationship between the independent and dependent variables. It ensures that the observed effects are due to the manipulation of the independent variable and not due to other factors such as confounding variables, selection bias, or measurement errors. This concept is crucial in research design to establish a clear cause-and-effect relationship.

Option Analysis:

Option A: External validity refers to the extent to which the results of a study can be generalized to other settings, populations, or times. This is not the focus of the question.
Option B: Generalizability is related to external validity, which concerns the applicability of the study's findings to broader contexts. This is not the focus of the question.
Option C: Internal validity is the correct answer as it pertains to the extent to which the study's results are due to the manipulation of the independent variable and not extraneous variables.
Option D: Population validity is not a standard term in research design. It may be confused with external validity, which is about generalizability to a broader population.

10. What is the purpose of research design?

Correct Answer: Correct answer is: (C) The purpose of research design is to provide a framework for conducting a study and collecting data.
