In a study of the effects of taste (salty; sweet; bitter) on eating, all possible orders of the experimental conditions are arranged in every possible sequence, and an equal number of participants are assigned to each sequence of tastes. This is an example of a design

Complete counterbalancing design.

Explanation

In a normal research design the treatment of experimental conditions of a subject will determine the outcome of the research and because many conditions are not tried out, a negative response is usually encountered due to external factors that may not be considered. To counteract this,  a counterbalanced design, is adopted  which measures all possible treatments and experimental conditions of a subject. this is done by the researcher arranging the subjects to every possible sequences and tasting for all conditions. This is a very good method to avoding errors since all subjects are exposed to all possible treatments.

Here, In a study of the effects of taste (salty; sweet; bitter) on eating, all possible orders of the experimental conditions are arranged in every possible sequence, and an equal number of participants are assigned to each sequence of tastes. This represents a Complete Counterbalancing design
