Factorial experiment

In statistics, a full factorial experiment is an experiment whose design consists of two or more factors, each with discrete possible values or levels , and whose experimental units take on all possible combinations of these levels across all such factors A full factorial design may also be called a fully crossed designSuch an experiment allows the investigator to study the effect of each ....
