Fisher, even though Operating for the Rothamsted experimental station in the sphere of agriculture, created his Rules of experimental design during the 1920s as an exact methodology for the correct design of experiments. Among his main ideas, was the significance of randomization—the random assignment of people to unique teams for that experiment;[32] replication—to cut back uncertainty, measurements should be recurring and experiments replicated to determine sources of variation;[33] blocking—to rearrange experimental units into teams of units that are similar to one another, and thus decreasing irrelevant resources of variation; use of factorial experiments—successful at evaluating the effects and feasible interactions of a number of independent factors.[22]
