PDF Notes: Second lecture of MMT

What defines nominal level of measurement?

Values serve only as labels without order or magnitude.

How does ordinal level of measurement differ from nominal?

Ordinal includes rank order but lacks equal intervals.

What is a key characteristic of interval level measurement?

Distances between values are equal, but zero is arbitrary.

What distinguishes ratio level measurement from interval?

Ratio has an absolute zero point and supports all mathematical operations.

What is reliability in measurement?

Consistency of results across different conditions.

What is interrater reliability?

Different evaluators achieve the same results.

What does intrarater reliability assess?

A single evaluator produces consistent results over time.

What does validity mean in testing?

A test measures what it is intended to measure.

What is face validity?

Validity based on superficial judgment of measurement.

What is construct validity?

Validity based on theoretical support for a measurement's use.

What does content validity evaluate?

Relation of measurement items to their underlying constructs.

What is criterion-related validity?

Comparison of a measurement to a criterion for appropriateness.

What defines nominal level of measurement?

Values serve only as labels without order or magnitude.

How does ordinal level of measurement differ from nominal?

Ordinal includes rank order but lacks equal intervals.

What is a key characteristic of interval level measurement?

Distances between values are equal, but zero is arbitrary.

What distinguishes ratio level measurement from interval?

Ratio has an absolute zero point and supports all mathematical operations.

What is reliability in measurement?

Consistency of results across different conditions.

What is interrater reliability?

Different evaluators achieve the same results.

What does intrarater reliability assess?

One evaluator achieves consistent results across repetitions.

What does validity mean in testing?

A test measures what it is intended to measure.

What is face validity?

Validity based on the appearance of measuring what it claims.

What is construct validity?

Validity based on theoretical support for a measurement's use.

What does content validity evaluate?

Relation of measurement items to their constructs.

What is criterion-related validity?

Validity determined by comparing a measurement to a criterion.

What defines nominal level of measurement?

Values serve only as labels without order or magnitude.

Ratio has an absolute zero point and supports all mathematical operations.

What is reliability in measurement?

Consistency of results across different conditions.

What is interrater reliability?

Different evaluators achieve the same results.

What does intrarater reliability ensure?

The same evaluator gets consistent results over time.

What does validity mean in testing?

A test measures what it is intended to measure.

What is face validity?

Assumed validity based on superficial appearance.

What is construct validity?

Validity based on theoretical support for a measurement.

What does content validity assess?

Relation of measurement items to their constructs.

What is criterion-related validity?

Measurement compared to a criterion for appropriateness.
