Let XB and XA denote, respectively, the weight of a person before and after a certain weight loss diet regime. If D = XA- XB, then the mean of the differences, D, calculated on a random sample of size n, can be used as a basis to test Ho: µD = 0 against H1: µD > 0 and thus verify if the weight loss diet has been effective. A t-test statistic is usually built as the ratio of an estimator of the population parameter of interest (or a function of the population parameters of interest in the case of the difference of two means), divided by its standard error. A significant treatment-by-block interaction in the ANOVA for an RCBD with more than one replicate per treatment per block indicates that differences among treatments are not constant from block to block.
