WebMar 19, 2004 · To see this, note that both designs have resolution greater than 5 and thus have all main effects and two-factor interactions estimable assuming that three-factor interactions and higher are negligible. Addelman’s design has only one subplot two-factor interaction at the whole-plot level, whereas the design in Table 2 has two. This ... WebEach effect in a 2 k model has one degree of freedom. In the simplest case, we have two main effects and one interaction. They each have 1 degree of freedom. So the t statistic is the ratio of the effect over its estimated standard error (standard deviation of the effect).
