An intelligence test yields the same results when administered on three separate occasions. However, the test’s results are more
strongly correlated with hours spent doing homework than they are with other standardized intelligence tests. This test has________ reliability and ________ validity.
Reliability: In psychological research, it refers to the constancy of a measuring test or a research study.
Example: If a boy measures the weight of himself during the line of a day he would expect to get a similar reading. Scales that measured the weight differently every time would be of very little use.
Validity: This is a measurement of how well a test or phenomenon measures what it asserts to measure. A test needs to be valid to get the results accurately interpreted and applied.
