HYPOTHESIS TESTING Lesson: Analysis of Variance and Post-Hoc Test An experiment was conducted to determine whether there is a significant difference among the mean increases in growth produced by five inoculins of growth for plants. The experimental material consists of 20 cuttings of a shrub (all of equal weight), with four cuttings randomly assigned to each of the five different inoculins. The results of the experiment are given in the table; all measurements represent an increase in weight (in grams). Test using.
