ABSTRACT
This chapter on sample surveys gives preliminary details about a survey, operational problems including development of schedules and training of investigators, stratification at different stages, identification of selected units in any stage of a multi-stage sampling design and arrangement for scrutiny and editing of data. Important sampling designs in common use are just passingly mentioned. The use of cohort or panel surveys, their limitations and modifications is discussed. A brief review of chain sampling and of randomized response technique has been added. A distinctive feature of the book that has been preserved in this chapter is to indicate interesting problems of research that still await complete or even partial solutions. Problems of strata construction and allocation of sample size across strata (partly studied by the author besides several others), problems of determining the sample size, and a few other theoretical problems have been hinted at for the benefit of research workers
