Choosing an experimental design
Contents of
Section 3
This section describes in detail the process of choosing an experimental
design to obtain the results you need. The basic designs an engineer
needs to know about are described in detail.
Note that
this section
describes
the basic
designs used
for most
engineering
and
scientific
applications
