Definitions:

Degrees of Freedom

The number of independent pieces of information available to estimate another piece of information, often related to sample size in statistical analyses.

Chi-squared Distributed

Pertains to a statistical distribution one typically employs to evaluate the goodness-of-fit of observed data with theoretical expectations.

Randomized Block Model

A statistical model used to remove the variability caused by known but irrelevant variables by grouping similar experimental units.

Nonparametric Counterpart

An equivalent statistical method or technique that does not assume the data follows any specific fixed distribution, often used as an alternative to traditional parametric tests.
