Summary: Experimental unit - The unit to which the treatment is applied. (only one is true) A) A good experiment includes systematic variation of one or more independent variables. My first experiment tested [herbicides] by experimentally changing [from applying herbicides in certain plots] and observing the effects on [the Simploids]. It accounts for the variation we expect to exist in nature. LAB SimUText Experimental Design Synthesis (20 pts), This document contains the synthesis questions for the, assignment.
