To introduce the student to the principles and methods of statistical analysis of designed experiments.


Experiments are carried out by researchers in many fields including biology, medicine, chemistry, physics, engineering and agriculture. In such experiments the results are affected both by the choice of factors to study and experimental error (such as measurement error or inherent randomness between experimental units). Choosing a good experimental design ensures that the aim of the study where it is used is achieved. Moreover, the statistical analysis of data collected from such designed experiments is simple, easier to interpret and the experimental resources are spent most efficiently. The main principles for designing and analyzing experiments will be introduced. Various standard experimental designs and the analysis of data obtained using them are covered. Criteria for optimality of experimental designs will be introduced. Methods for constructing nonstandard designs when the model is linear or nonlinear in the parameters will be presented.

Learning outcomes

On successful completion of this course unit students will

given the description of how a set of data were collected, be able to:

  • recognise what design was followed,
  • &comment on the shortfalls of the design used,
  • &decide what assumptions are appropriate in modelling the data,
  • perform the appropriate analysis;

be familiar with the principles of:

  • randomisation and replication,
  • nested designs,
  • block designs,
  • factorial designs and fractional layouts
  • response surface designs.

Feedback methods

Feedback tutorials will provide an opportunity for students' work to be discussed and provide feedback on their understanding.  Coursework or in-class tests (where applicable) also provide an opportunity for students to receive feedback.  Students can also get feedback on their understanding directly from the lecturer, for example during the lecturer's office hour.
