Question

Psychologists who develop new tests and questionnaires to be used in research and diagnosis must insure that these measures are reliable. In other words, they must insure that the measures yield consistent results time and again. To do this, psychologists administer the measure to a group of participants, and then administer the measure again to the same group of participants days, weeks or months later. This demonstrates whether or not the measure consistently yields a similar result for the same person.

Here are the data for such a reliability analysis:

X	Y
67	69
88	72
74	88
96	96
85	89
47	76
