Key Concepts

Variable

A variable is a characteristic or property that can differ among experimental units and that is measured or observed in a study. Variables may be quantitative, like the number of errors on an exam, or qualitative, like gender or color, and they serve as the primary data points for analysis.

Experimental Unit

The experimental unit is the basic entity or subject on which measurements are taken in a study. It represents the smallest division of the experimental material such that any two units may receive different treatments or have different characteristics measured. Clearly defining the experimental unit is crucial for ensuring that observations are independent and for accurate data analysis.
