It refers to a plan for assigning subjects to experimental conditions and the statistical analysis with the plan. The design of an experiment to investigate a scientific or research hypothesis involves a number of interrelated activities: 1. Formulation of statistical hypothesis, 2. Determination of the experimental conditions to be used, and 3. Specification of the number of subjects required.
