Q1: A measure that does not yield consistent scores and does not measure what it is supposed to measure is ____.	Answer: Neither valid nor reliable Explanation: If a measure is inconsistent and does not measure what it should, it lacks both reliability and validity.
Q2: Rosalyn’s measure of intelligence is best described as a(n) ____ scale.	Answer: Interval Explanation: Intelligence scores are measured on an interval scale, where the intervals between scores are meaningful, but there is no true zero.
Q3: Checking whether the new measure differs from those it should differ from provides an assessment of ____ validity.	Answer: Discriminant Explanation: Discriminant validity ensures that the test is unrelated to measures it should not be related to.
