Document Summary

Reading e: retest consistency agreement review sheet. Systematic bias form of measurement error that changes every score in the same direction and by a constant amount. Consistency coefficient indicates the degree to which scores differ as a result of unsystematic error. Agreement coefficient indicates the degree to which scores differ as a result of a combination of unsystematic error and systematic bias. Standard confidence interval calculated based on the level of confidence and the amount of unsystematic error (set using a z score). Consistency standard error estimates the amount of unsystematic error and is based on the variances and consistency coefficient of the scores. Asymmetric confidence interval an adaptation of the standard confidence interval to address the combined effect of unsystematic error and systematic bias. Agreement standard error calculates the asymmetric confidence interval to widen the biased side of the confidence interval and is based on the variances and agreement coefficient of the scores.
