Essay

TABLE 11-6
An agronomist wants to compare the crop yield of 3 varieties of chickpea seeds. She plants all 3 varieties of the seeds on each of 5 different patches of fields. She then measures the crop yield in bushels per acre. Treating this as a randomized block design, the results are presented in the table that follows.
-Referring to Table 11-6, what are the degrees of freedom of the randomized block F test for the difference in the means at a level of significance of 0.01?

Definitions:

Degrees Of Freedom

Degrees of freedom refer to the number of values in a statistical calculation that are free to vary when estimating some kind of parameter, influencing the shape of various statistical distributions.

Population Variance

A measure of the dispersion of all the values in a population, calculated as the average of the squared differences from the population mean.

Confidence Interval

An interval estimate around a sample mean within which an unknown population mean is expected to lie, at a certain confidence level.

Population Mean

The average of a set of characteristics, quantities, or values for all individuals or items in a defined population.
