16
Q

concerns to the degree to which ‘two or more independent observers or coders agree about scoring’

A

equivalence

17
Q

Two types of equivalence:

A

alternative form
inter-rater/intra-rater reliability

18
Q

when the ‘design calls for observation’ and is used to determine whether two observers using the same instrument at the same time will obtain similar results

A

inter-rater/intra-rater reliablity

19
Q

two tests are developed based on the same content

A

alternative form
