Which type of reliability exists when consistency of observation, measured by a correlation coefficient, is noted between two or more research assistants who record their observations of an event at the same time?
A) Internal consistency
B) Parallel forms
C) Test-retest
D) Interrater

Question

Quizplus · Accepted Answer

Interrater reliability refers to the consistency or agreement of observations made by two or more raters or observers. In the given scenario, research assistants are recording their observations of an event at the same time, and the consistency of their observations is measured by a correlation coefficient. This is an example of interrater reliability, as it is assessing the consistency between different raters. The other options listed are different types of reliability, but they are not relevant to the scenario described. Internal consistency refers to the degree of consistency between different items or questions within the same measure. Parallel forms reliability refers to the degree of consistency between different versions of a measure. Test-retest reliability refers to the consistency of scores on a measure over time.
