Experimental

activities are involved in the design:

statistical hypotheses that are germane the
scientific hypothesis. A statistical
hypothesis is a testable formulation of
scientific hypotheses. They are statements about
either the parameter(s) of a population or the
functional form of a population.
(b) Determination of to the experimental conditions
(independent variable) to be used, the measurement
(dependent variable) to be recorded, and the
extraneous conditions (nuisance variables) that
must be controlled.
(c) Specification of the number of subjects
(observational units) required and the population
from which they will be sampled.
(d) Specification of the
procedure for assigning the subjects to the
experimental conditions.
(e) Determination of the
statistical analysis that will be
performed.
