Types of Validity - IB HL Psychology

Questions and Answers

What is the definition of Internal Validity?

The measure of the experimenter's measurement of the dependent variable. (correct)

Refers to the extent to which the findings are valid over time.

Refers to the extent to which a study appears to measure what it claims to measure.

Refers to the extent to which the results and conclusions are generalisable to real life.

What does Ecological Validity refer to?

The extent to which the findings are applicable to real-life situations. (correct)

The accuracy of diagnoses made about conditions.

The degree to which the sample represents the population.

The statistical significance of the results.

What does Population Validity refer to?

Study Notes

Internal Validity

Measures how accurately an experiment assesses the dependent variable.

Ecological Validity (External Validity)

Assesses the generalizability of study findings to real-life scenarios.

Population Validity (External Validity)

Evaluates how well the sample represents broader populations.

Temporal Validity

Considers the validity of findings over time, accounting for changes and developments.

Face Validity

Determines if a study seems to measure what it claims at first glance.

Construct Validity (Test Validity)

Encompasses two aspects:
- Convergent Validity: Assesses the relationship between related constructs.
- Discriminant Validity: Tests that unrelated constructs do not show any relationship.

Content Validity (Test Validity)

Evaluates whether a study or test measures all aspects of a concept comprehensively.

Criterion Validity

Compares study results and conclusions to other measures for validation.

Predictive Validity

Assesses the ability of findings to forecast real-life outcomes or applications.

Concurrent Validity

Examines whether study results align with findings from other related studies.

Statistical Conclusion Validity

Ensures results are statistically significant, establishing cause and effect beyond mere chance.

Representation Validity (Translational Validity)

Evaluates how well the studied construct can be applied to real-world situations.

Diagnostic Validity

Assesses the accuracy of a diagnosis concerning a specific condition.

Instrumental Validity

Evaluates the appropriateness of tools used to measure dependent variables for accuracy.
