Credit points: 15

Subject outline

Students will learn to design and analyse experiments in the life sciences and agriculture. The topics covered in this subject include a brief review of non-parametric methods; randomisation, blocking and randomised block designs; one-way and two-way layouts; multiple comparison procedures; fixed and random effects; mixed models; multiple linear regression; analysis of covariance; factorial designs; fractional factorial designs; and an introduction to cluster analysis. This subject makes use of the freely available software package R. STA2BS is co-taught with STA3BS

Graduate capabilities & intended learning outcomes

01. Present clear, well structured and rigorous proofs of important fundamental linear model results. This includes appropriate use of statistical and mathematical vocabulary and notation.

Activities:
Weekly problem classes involve theoretical derivations of results introduced in lectures. 10 almost weekly assignments include some questions with theoretical derivations. The second hour of the problem class allows for students to work through the assignment questions with guidance from the lecturer and fellow students.

02. Formulate appropriate hypotheses and experimental designs.

Activities:
Formulation of hypotheses is discussed and modelled via example in lectures. Experimental design concepts are discussed in lectures and weekly problem classes involve derivation of key theoretical and applied components to design of experiments. Assignments earlier in the semester largely involve hypothesis testing. Assignments later in the subject involve a mixture of hypothesis testing and experimental design. The second hour of the problem class allows for students to work through the assignment questions with guidance from the lecturer and fellow students.

03. Utilize randomization and blocking appropriately in the design of statistical experiments.

Activities:
Randomization is a key component to much of the theory throughout the entire subject and is modelled/discussed in lectures and implemented by the students in weekly problems under guidance from the lecturer. Similarly, blocking is considered in weeks 3-6. Assignments consist of both theoretical derivations and applications to actual data sets. The second hour of the problem class allows for students to work through the assignment questions with guidance from the lecturer and fellow students.

04. Construct statistical experiments using factorial and fractional factorial designs with an emphasis on the construction of simple estimators of effects associated with two-level factors.

Activities:
Introduced in lectures in weeks 10 and 11. Key applications of theoretical results are shown during the problem classes of these weeks. Assignments 8 and 9 involve the student designing/recognising factorial and fractional factorial designs. The second hour of the problem class allows for students to work through the assignment questions with guidance from the lecturer and fellow students.
