Abstract:
|
Blocks, strata, and covariates may be used to reduce variance to provide a better test for treatment effects of interest. Sometimes the terms are used interchangeably. However, each concept has different processes and assumptions attached. We will discuss the underlying assumptions, uses in experimental design, and possible analyses when blocks, strata, or covariates are used.
