Answer #1

Answer: c. Parallel-forms reliability

After getting results from the experiment, we can't believe those results confidently. Some times, those results maybe because of the third variable. If that is true, our experiment suffers from reliability and validity. So we should check those results again. If again results are the same, then we can believe our experiment has reliability.

Parallel-forms reliability is a method to test reliability. In this method, We will do two different tests on the same participants. If scores in two tests are correlated with each other. Then that experiment has reliability. In the given case, exactly this has happened. That's why it comes under Parallel-forms reliability.

6. A math teacher gives two different tests to measure students' aptitude for math. Scores on the first test are normally distributed with a mean of 23 and a standard deviation of 4. Scores on the second test are normally distributed with a mean of 64 and a standard deviation of 10. Assume that the two tests use different scales to measure the same aptitude. If a student scores 29 on the first test, what would be his equivalent score...

In a study of how external clues influence performance, university professors gave two different forms of a midterm tests to a large group of introductory students. The questions on the test were identical and in the same order, but one test was printed on blue paper and the other on red paper (Teaching Psychology, May 1998). Grading only the difficult questions on the test, the researchers found that scores on the blue test had a distribution with a mean of...
