Study Notes

Predicting Future Behavior

Behavioral samples are used to forecast future behaviors, such as job applicant performances.
Current testing methods struggle to accurately replicate a person's state of mind.
Tests exhibit variable success in predicting behaviors; some, like workplace performance, work well, while others, such as violent behavior, do not meet expectations.

Limitations of Testing

Competent testers must recognize the limitations of specific assessments and seek complementary data.
Error variance occurs when factors unrelated to the intended measure impact test results.

Sources of Error in Assessment

Error variance encompasses components unrelated to the ability being measured and stems from various sources:
- Test constructor biases
- Test administrant issues, including emotional state and environment
- Scoring and interpretation discrepancies.

Reliability in Testing

Reliability refers to the consistency of a measuring tool, signified by the reliability coefficient.
Total variance = True variance + Error variance, with reliability coefficients indicating the proportion of true variance.

Construct and Criterion Validity

Construct validity ensures that the test genuinely measures what it claims.
Evidence includes test homogeneity and expected variations in scores due to theoretical manipulations.
Criterion-related validity employs a validity coefficient that correlates test scores with an outcome measure.

Characteristics of Quality Tests

Essential technical criteria for test quality encompass reliability and validity.
Adequate norms are critical for comparison against peer performances.

Norms in Testing

Norm-referenced testing compares individual scores to a normative sample, establishing a performance reference.
Criterion-referenced testing evaluates an individual's performance against a specified standard.

Practical Implications of Tests

Test utility assesses the practical value and usefulness of the testing process.
Examples of criterion-referenced testing include assessments for high-school diplomas or driving skills, mandating specific competency levels.
