Sampling Problems in the Evaluation of Agricultural Development Projects in Pakistan

Abstract

Several projects have been implemented in Pakistan with an aim of introducing positive change in various sectors of economy' such as agriculture, industry, services, etc. Although several bench mark surveys have been conducted in Pakistan but the main emphasis in this article has been given to the sampling problems involved in surveys carried out to evaluate the development projects in the field of agriculture. Response errors and errors introduced due to the bias of interviewers are the major sources of errors in our sample surveys. However, in these pages, attention has been focussed only to the situations where we fail to capture the real responses of various inputs of the projects due to the lack of a proper sampling plan
