To quickly assess the difficulty of the text, read a short excerpt:
This is equivalent to the usual "t test" for the equality of two correlated means. 29. FOOTNOTES 6. ANOVA methods for estimating reliability from multiple repeated measurements are presented in Winer [36, pp. 124-130] under the assumption that the true and error variances and hence the • ^ reliability of the measure are the same for each round of measurement. The conditions necessary for reliability to be constant across more than two sets of repeated measurements are that all observed score va...riances must be equal and all their covariances must also be equal. See [30] for discussion of an appropriate test of this composite hypothesis. Wiley and Wiley [35] have developed a method for estimating non-constant reliabilities from three or more waves of repeated measurements for a situation where the process of change can be modelled in terms of linear relationships between adjacent true scores and where error variances remain constant. 7. This judgement needs to be qualified because the measure used in [2, 21] is a ratio of the coupon redemption for the exposed groups to that for the control group.
