Degrees of Freedom

The number of independent pieces of information available to estimate another piece of information or the parameters of a model.

Treatments

The conditions or interventions applied to participants in an experimental study.

F-Test

An F-test is a type of statistical test that compares the variances of two populations to determine if they are significantly different from each other.

Randomized Block Design

Randomized block design is a statistical experiment design that aims to reduce variation by grouping similar experimental units into blocks before randomly assigning treatments within blocks.
