This yields two To review correlation, see scores for each examinee. Computing a correlation for the relationship between the two sets of Exercises 4.1 and 4.2. To scores indicates the stability of the scores over time. For instance, a high correlation indicates review R and percentage that those who scored high on the first administration also scored high on the second of explained variance, see administration. Likewise, those who scored low on the first administration also scored low on Exercises 4.6 and 4.7. the second administration. When a correlation is used to express the stability of test scores over time, the correlation is commonly referred to as a test- retest correlation or test-retest reliability or even as a reliability coefficient. Despite the different names, test-retest reliability is mathematically the same as a standard correlation. Just to make things a little more confusing, researchers sometimes simply use reliability when they mean test-retest reliability in particular. In such instances, the reader has to read the Method section to confirm what the researcher means by reliability. EXCERPT FROM THE RESEARCH ARTICLE! We assessed the reliability of the Behavioral and Emotional Rating Scale-Second Edition: Parent Rating Scale (BERS-2; PRS) All parents of kindergarteners through to second graders at the elementary school (N = 122) and sixth graders at the middle school (N= 169) received by mail a . . . copy of the PRS. . . Parents were informed that on receipt of the first protocol, a second PRS would be sent to them that was also to be filled out and returned. . . . A return rate of 26.8% was achieved. 0.220
