If a test has good test retest reliability, a, there is a strong correlation between items on the test.
00:09
B, it accurately measures what it says it measures.
00:13
C, it can be used to predict future performance.
00:16
Or d, the test yields similar scores if taken at two different times.
00:21
Here's what is test retest reliability.
00:24
The idea behind this is it's a way of checking the validity of the test, making sure that the measurement are actually representative of the person being measured.
00:33
So it's measuring or testing the same individual at two separate occasions and comparing the two.
00:44
So if they're very similar, you can say, okay, this test is actually measuring something representative of the person and not the situation they were in at the time...
