This course is concerned with the application of linear models to the
analysis of experimental data. This analysis seeks to identify the
underlying courses in the variation of the values of a response
variable, y, by identifying variations in various background variables.
The models assume normally distributed measurement errors and therefore
involve the normal, chi-squared, t and F distributions.
The analysis is greatly simplified if the explanatory variables are
orthogonal to one another. This can be achieved if the measurements made
are at carefully chosen combinations of the background variables. This
is the experimental design of the course's title. All the commonly used
designs will be studied in the course.
On completion of the course students should be able to:
-Identify a simple experimental design
-Construct an appropriate ANOVA table
-Perform multiple comparisons tests
-Utilize orthogonal polynomials
-Distinguish between fixed effects and random effects
-Construct full and partial factorial designs in the presence of blocks
