A researcher is interested in seeing what effect  a particular type of drug has on an intelligence test,  depending on the time of day that the pill is administered. The researcher computes a two-way ANOVA and plots  the resulting cell means on the graph at right. Assuming  that any obvious differences are statistically  significant Is there a main effect for type of pill? Is there a main effect for time of day? Is there an interaction? 4.
