CRD Statistical Analysis

Variability in CRD is composed of two Components

1. Due to treatment ( the factor being studied)
2. Due to experimental error
Demonstration on the use of ANOVA and F-test in CRD using 2 sets of
experimental data

1. Treatments with equal number of replications
2. Treatments with unequal replications

TREATMENTS WITH EQUAL NUMBER OF REPLICATIONS

For illustration purposes the data on the table below will be used.” Rice Yield
as influenced by varying rates of Nitrogen application” Computation is similar
to the Treatments with unequal number of replications but the only difference
is on the determination of the Treatment Sum of Squares tSS.
