experimental design in the following diagram (Box et al., 1978), is represented by a movable window through which certain aspects of the true state of nature, more or less distorted by noise, may be observed.
Design of experiment provides a method by which the treatments are placed at random on the experimental units in such a way that the responses are estimated with the utmost precision possible. There are three basic principles of design which were developed by Sir Ronald A. Fisher.
For Becky who helped me all the way through and for Christie and Erica who put up with a lot while it was getting done
Experimental Design: Statistical Analysis of Data. In previous chapters, we have discussed the basic principles of good experimental design. Before examining specific experimental designs and the way that their data are analyzed, we thought that it would be a good idea to review some basic principles of statistics.
The simplest true experimental designs are two group designs involving one treatment group and one control group, and are ideally suited for testing the effects of a single independent variable that can be manipulated as a treatment.
