Reliability in Assessment Procedures

Reliability refers to:

• Accuracy of test content

• Consistency of test scores

• Validity of interpretation

• Standardisation of norms

Reliability refers to:

• Instrument itself

• Test manual

• Test results or scores

• Testing room

Observed score is defined as:

• True score only

• Measurement error only

• True score + Measurement error

• True score - Measurement error

Which is the largest source of measurement error?

• Time sampling error

• Content sampling error

• Interrater differences

• Test length

Practice effect is associated with:

• Content sampling error

• Time sampling error

• Interrater differences

• Test administration

A reliability coefficient closer to 1.0 indicates higher test consistency.

• True

• False

Test-retest reliability is most appropriate for measuring:

• Mood

• Temporary stress

• Personality traits

• Daily behaviour

Alternate forms reliability is used to determine:

• Internal consistency

• Stability over time

• Equivalence between two forms

• Rater agreement

Simultaneous administration of alternate forms helps reduce:

• Content sampling error

• Practice effect

• Interrater differences

• Test length effect

Interrater reliability measures:

• Stability across time

• Consistency between test items

• Agreement between raters

• Equivalence of forms
