Concept notes: Correlational research examines the relationship between two or more variables to determine if they are associated or correlated. It does not establish causation but rather looks at the strength and direction of the relationship.

Common Mistakes: A common misunderstanding is that correlational research can establish causation. However, it only indicates the presence of a relationship, not the cause-and-effect relationship.

Explanations: The study aims to find the significance of the association between job performance and commitment. This aligns with the definition of correlational research, which investigates the relationship between variables without manipulating them. The goal is to determine if there is a significant correlation between job performance and commitment, not to establish causation.

Option Analysis:

Option A: Correct. Correlational research is appropriate for studying the relationship between job performance and commitment.
Option B: Incorrect. Experimental research involves manipulating one variable to determine its effect on another, which is not the case here.
Option C: Incorrect. Descriptive research describes characteristics of a population or phenomenon but does not investigate relationships between variables.
Option D: Incorrect. Historical research involves the study of past events and is not relevant to the current context of investigating a relationship between variables.

Correct Answer: Correct answer is: (D) Examine associations without inferring causation.

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

Difficulty: Moderate

Concept notes: Correlational research is a type of non-experimental research method that aims to find relationships between variables without manipulating them.

Common Mistakes: A common misunderstanding is that correlational research can establish cause-and-effect relationships, which it cannot.

Explanations: Correlational research examines the relationship between two or more variables to determine if they are associated. However, it does not manipulate variables or establish causation. The goal is to identify patterns and associations, not to infer that one variable causes changes in another.

Option Analysis:

Option A: This describes descriptive research, not correlational research.
Option B: This describes experimental research, not correlational research.
Option C: This describes experimental research, which aims to establish cause-and-effect relationships.
Option D: This correctly describes correlational research, which examines associations without inferring causation.

5. What is meant by "Internal validity" in the context of research?

Correct Answer: Correct answer is: (C) Whether other factors during the data collection period impacted the results.

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

Difficulty: Moderate

Concept notes: Internal validity refers to the extent to which a study establishes a causal relationship between the independent and dependent variables, free from the influence of extraneous variables.

Common Mistakes: A common misunderstanding is confusing internal validity with external validity, which concerns the generalizability of the results to a broader population.

Explanations: Internal validity is concerned with the accuracy of the causal inference within the study itself. It ensures that the observed effects are due to the manipulation of the independent variable and not due to other factors that may have influenced the results during the data collection period.

Option Analysis:

Option A: This describes external validity, which is about the generalizability of the results to the broader population.
Option B: This describes reliability, which is about the consistency of the measuring instrument.
Option C: This correctly describes internal validity, which focuses on whether other factors during the data collection period impacted the results.
Option D: This describes ethical considerations, which are important but not related to internal validity.

6. In what criterion in evaluating sources does this statement "Is the contact information, such as the publisher or e-mail address available?" belong?

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