Question

Two-Way Classification Designs

An experiment was designed to test the effects of five levels of phosphate
fertilizer (P1, P2, P3, P4, and P5) on the yield of potato tuber dry matter. The experiment was
laid out in the field as a 5x5 Latin square, and the following yields (kg DM/plot) were obtained: (see pic)

1. Compute the relative efficiency of this design over CRD and RCBD.

2. Obtain the descriptive statistics for each type of fertilizer

Statistics that help describe, summarize, and present information extracted from data. Descriptive statistics include concepts related to measures of central tendency, measures of variability, measures of frequency, shape of distribution, and some data visualization techniques/tools such as pivot tables, charts, and graphs.
