Question

Jupiter pilots his newly created perfectionism scale on a high school psychology class. He returns one month later to administer the same test to the same students, and then correlates the two sets of results. What is Jupiter probably doing?

A) Testing the reliability of his scale
B) Testing the validity of his scale
C) Testing the intelligence of the students
D) Testing the ethical standards of the school

Answer 1

Jupiter is testing the reliability of his perfectionism scale by comparing the results of two administrations of the test to the same students one month apart.

Step-by-step explanation:

Jupiter is likely testing the reliability of his newly created perfectionism scale. Reliability refers to the consistency of a test over time. By administering the same test to the same group of students after one month and correlating the two sets of results, he can determine if the scale gives consistent results over time. This is a common technique used in psychological research to assess an instrument's quality and trustworthiness.
