A Different Look at Analysis of Variance and Design of
Experiments
Beginning courses on statistical methods are not
favorites of unsophisticated students. Beginning students often feel
engulfed by sets of formulas and at best learn how to substitute
numbers into those formulas. We suggest bypassing all of this with one
simple program. The user does not need to know any details of the
experimental design, only the treatment applied to each experimental
unit. A number of examples will be given. We now teach analysis of
variance not design of experiments. Simplification of the details of
statistical analyses will leave time to teach real design of
experiments. Some comments on how to do this will be given and
suggestions from the audience solicited.
