Completely Randomized Single Factor Experiment

A completely randomized single factor experiment is an experiment where both:

• One factor of two or more levels has been manipulated. For example, the experiment may be investigating the effect of different levels of price, different flavors, or different advertisements. Where two factors are manipulated, such as both price and flavor being varied, it is then a multifactor experiment and not a single factor experiment.
• Each respondent in the survey is shown one and only one of the levels of the factor. For example, each respondent may be shown a single product concept, one of the multiple alternative advertisements, or one of the multiple pricing structures. In the language of statistics, this is referred to as a completely randomized design.
