Scenario A:
Dr. Jones administers a job-skills test to 100 job applicants. The company then hires the 50 applicants who had the highest scores on the test. Among these 50 applicants, after they have been employed at the company for 6 months, those who scored higher on the job-skills test are performing substantially better on the job.
Scenario B:
A psychologist a computer-based test to 140 college students. The test is designed to measure the student students unconscious prejudice towards certain groups. Each student takes the same test a second time, 3 weeks later. There is a very high correlation between students test scores on the two occasions: Higher Scores on the first test administration are strongly associated with higher scores on the second test administration.
Scenario C:
Dr. Suzuki has developed a psychological test to ensure people's general level of optimism. Research consistently shows that scores on Dr. Suzuki optimism test are most highly correlated with scores on other psychological tests of optimism and, as predicted by theory, are only weakly correlated with scores on tests that measure the degree to which people tend to give socially desirable answers to questions (i/e., answers that they think are socially appropriate and that other people "want to hear").
