Fisher's Sugar Beet Data

Description

A classical 3 by 2-cubed randomized block experiment in four blocks of size 24. The response is the total weight of sugarbeet roots off the plot, but this is accompanied by the number of roots measured. The suggestion is that number of roots should be a covariate to allow for varying plot size.

Value

The factors are Variety (3 levels, a, b and c), and N, P and K each at 2 levels, present or absent.

The data frame contains the following components:
Block Block number, I, II, III or IV
V Variety
N Nitrogen present/absent
P Phosphorous present/absent
K Potassium present/absent
No Number of roots
Wt Weight

CATEGORY

Analysis of variance and covariance.
