AIM: To design a multifactor experiment, collect data, graphically analyse the data,
and derive appropriate, actionable conclusions from the analysis.
Before attempting this assignment, please read through unit 5, the related book
chapters, especially Khan (2013) section 10.5 (Fractional Factorial Designs)
Design, perform and analyse a multifactorial experiment of your own devising based
on the material presented for designed experiments. In this assignment, you are
expected to conduct your own experiment, using a fractional factorial design.
Include four experimental factors, and keep the number of levels for each factor to
two. Use a half fraction of a full factorial, i.e. 24-1
factorial design, meaning that you
will have eight (8) experimental trials. Your design matrix should therefore look like
the one shown on page 440 of the Khan e-textbook (below).
