Interscorer Reliability Wechsler Preschool and Primary Scale of Intelligence

Interscorer reliability is usually judged by having a set of examinees' responses to the test scored by two or more scorers and correlating the two sets of scores by computing a correlation coefficient. Note that when a correlation coefficient is used for this purpose, it is called an "interscorer reliability coefficient." See Appendix A to review the correlation coefficient before attempting this exercise.
