Sampling Techniques
The students would be exposed to elementary and two stage sampling techniques. It would help them in understanding the concepts involved in planning and designing their surveys, presentation of survey data analysis of survey data and presentation of results.
Planning, execution and analyses of small large and sample surveys with illustrative examples. Errors in survey, sources of non-sampling errors, remedial of non sampling errors, Basic principles of sampling, Simple random sampling with and without replacement.
Stratified Sampling, Systematic Sampling, Cluster sampling (with equal and unequal size clusters), rational behind use of unequal probability sampling : probability proportional to size with and without replacement method (including cumulative total method and lahiri's method)
Use of Auxiliary Information: Ratio, product and regression methods of estimation, their comparisons among them and with sampling without replacement. Concept of double sampling and its use in ratio, product and regression method of estimation.
Two stage sampling with equal and unequal number of second stage units.Horvitz Thompson estimator (HTE) of a finite population total/mean and expression for variance of HTE and its unbiased estimator due to Horvitz-Thompson and Yates & Grundy.
Related estimators of finite population mean (Hansen-Horwitz, Desraj’s estimators for general sample size)Theory of multi-stage sampling with varying probabilities (with or without replacement) due to Durbin. Narain and Sukhatme sampling schemes.
