Two Psychometricians (Educators Who Are Experts in the Field of Psychological

Question 26

Essay

Two psychometricians (educators who are experts in the field of psychological test design) were asked to rank six designs for a new standardized college entrance exam. Two psychometricians (educators who are experts in the field of psychological test design) were asked to rank six designs for a new standardized college entrance exam. This problem uses Spearman's rank correlation coefficient to see if there is a (positive) relationship between the educators' rankings. The null and alternate hypotheses are as follows: (There is no association between the rank pairs) (The correlation between the rank pairs is positive) Describe why the test statistic is called the rank correlation coefficient. ________________________________________________________ Test Statistic: = ______________ Rejection region (for = 0.05): Reject if > ______________ Conclude: ______________ There ______________ sufficient evidence to indicate there is any significant positive correlation between the educators' rankings. What does this result mean in the context of the problem? ________________________________________________________ What is the observed significance level for this test? ______________ This problem uses Spearman's rank correlation coefficient to see if there is a (positive) relationship between the educators' rankings.
