... including both additive and multiplicative treatment effects. Mee and Chua 8 proposed a regression-based test as an alternative to paired t-test for truncated samples. Since the effect of any treatment is likely to be related to the initial level in a multiplicative model, it seems preferable to an ...

Because reliability tends to decrease as the length of a test decreases, the split-half reliability coefficient usually underestimates a test's true re ...

Otherwise, the null hypothesis is not rejected. Critical F is obtained by first noting that the numerator degrees of freedom for the an ...
