Which of the following statements is NOT correct?
A test-retest reliability coefficient of zero indicates perfect test-retest reliability.
The test-retest reliability coefficient is the correlation between the first and second administration of the test.
The closer each respondent’s scores are on T1 and T2, the more reliable the test measure.
In order to measure the test-retest reliability, we have to give the same test to the same test respondents on two separate occasions.

coefficient criterion.
linear coefficient.
correlation coefficient.
coefficient of determination.
correlation coefficient.
