Homework Help: IQ Test ?

Posted by Melissa on Wednesday, October 17, 2007 at 1:32pm.

A group of people took a new IQ test twice. Nearly all of those who did well the first time they took it also did well the second time. Nearly all those who did poorly the first time did poorly again the second time. Therefore, this test has __ reliability and __ validity.


a. high...high
b. low...low
c. high...unknown
d. unknown...high

I chose answer C. because in order to be reliable, the test scores are repeated. But this question was somewhat difficult to read, so i was wondering if this was the correct answer.
