The results of sample surveys through opinion polls are commonplace in newspapers and on television. The objective of the Sampling Theory section of the module is to introduce several different methods for obtaining samples from finite populations. Experiments which aim to discover improved conditions are commonplace in industry, agriculture, etc. The purpose of experimental design is to maximise the information on what is of interest with the minimum use of resources. The aim of the Design section is to introduce some of the more important design concepts.
Prerequisites: MAS223 (Statistical Inference and Modelling); MAS367 (Linear and Generalised Linear Models) recommended
No other modules have this module as a prerequisite.
- This course deals with two different areas where the important features are the planning before the data are collected, and the methods for maximising the information which will be obtained. The results of sample surveys through opinion polls, etc., are commonplace in newspapers and on television. The Sampling Theory component of the course introduces several different methods for obtaining samples from finite populations and considers which method is most appropriate for a given sampling problem. Experiments which aim to discover improved conditions are commonplace in industry, agriculture, etc. The purpose of experimental design is to maximise the information on what is of interest with the minimum use of resources. The Experimental Design component of the course introduces some of the more important design concepts.
- To consolidate some previous mathematical and statistical knowledge.
- To introduce statistical ideas used in sample surveys and the design of experiments.
- recognise the possible pitfalls in published survey data; and understand the need for randomness and the desirability of stratification in sampling;
- understand the main stages in experimental research and know the desirable properties and the criteria of optimality of experimental designs;
- understand the main features of block designs, factorial and fractional factorial designs and response surface design and know simple methods for their construction;
- understand the result of the General Equivalence Theorem and apply it to obtain optimum experimental designs;
