2³ - Factorial Experiment Analysis

1. The following table gives the layout and the results of a  2³ factorial design laid out in four replications. The purpose of the experiment is to determine the effect of different kinds of fertilizers Nitrogen (N), Potash (K) and Phosphate (P) on potato crop yield. Analyse.
