Research aptitude Quiz 2 Reliability

Which type of reliability assesses the consistency of results across items within a test?

• Inter-rater reliability

• Test-retest reliability

• Split-half reliability

• Internal consistency reliability

What does test-retest reliability measure?

• Stability of test scores over time

• Consistency among items within a test

• Agreement between two raters

• Correlation between halves of a test

Which type of reliability is tested by giving the same test to the same participants on two different occasions?

• Internal consistency

• Test-retest reliability

• Parallel forms reliability

• Inter-rater reliability

Inter-rater reliability is relevant in which of the following situations?

• When two researchers measure the same behavior

• When a test is divided into two halves

• When the same test is administered twice

• When test items measure the same construct

If a researcher wants to ensure the reliability of scores in a test by splitting it into two parts and then comparing scores, which type of reliability are they testing?

• Test-retest reliability

• Split-half reliability

• Inter-rater reliability

• Internal consistency reliability

What type of reliability is being assessed when researchers use two equivalent versions of the same test?

• Test-retest reliability

• Internal consistency

• Parallel forms reliability

• Inter-rater reliability

Which method is used to check the internal consistency of a test?

• Test-retest method

• Cronbach's alpha

• Kuder-Richardson method

• Both B and C

A high Cronbach's alpha (e.g., >0.90) could suggest which potential issue in a research instrument?

• The test lacks reliability

• The test items are too similar, reducing the breadth of measurement

• There is insufficient correlation among test items

• The test is highly unstable over time

If a research instrument has high internal consistency but low test-retest reliability, what does this indicate?

• The instrument is reliable over time but not internally

• The instrument is reliable within a single test but may not be stable across time

• The instrument is inconsistent in its items

• The instrument has poor inter-rater reliability

When a researcher reports that an instrument has high "reliability," it means that the instrument

• Measures what it is intended to measure accurately

• Produces consistent results across time, items, or raters

• Is validated for the intended construct

• Is capable of measuring different constructs simultaneously
