This module considers the theory of finite sampling along with related matters of survey and questionnaire design. A sample survey will be carried out (and its results analysed) by the members of the class.
This module considers the theory of drawing samples from finite populations, and gives students experience of practical sampling.
On completion of this module, a student should be able to:
1. INTRODUCTION: Census and sample survey design. Population, sample and unit; sample frame; pilot surveys; startification. Bias and non-sampling errors; non-response.
2. FINITE SAMPLING THEORY: Basic ideas and theory of simple random sampling. Finite population corrections. Comparison of sampling designs. Quota, cluster, systematic and multistage methods of sampling.
3. EXAMPLES: Social, agricultural and industrial censuses and surveys. Questionnaire design.
4. ANALYSIS OF SAMPLE SURVEYS: Estimation of means, variance, totals, proportions in samples from finite populations; theory of simple random sampling, extensions to stratified sampling; optimal sampling when total sample size or total cost is fixed; models for cost functions. Use of additional information; ratio and regression methods of adjustment.
