SAMPLING TECHNIQUES & DETERMINATION OF SAMPLE . size IN APPLIED STATISTICS RESEARCH: AN OVERVIEW. Singh, Ajay S. Department of AEM, Faculty of Agriculture, University of Swaziland, Luyengo, Swaziland Masuku, Micah B. Department of AEM, Faculty of Agriculture, University of Swaziland, Luyengo, Swaziland Abstract Applied statistics research plays pivotal role in diverse problems of social sciences, agricultural sciences, health sciences, and business research. Many investigations are conducted by survey research. The technique of SAMPLING and DETERMINATION of SAMPLE size have crucial role in survey-based research problems in applied statistics. Specific SAMPLING TECHNIQUES are used for specific research problems because one technique may not be appropriate for all problems. Similarly, if the SAMPLE size is inappropriate it may lead to erroneous conclusions. The present paper gives an overview of some commonly used terms and TECHNIQUES such as SAMPLE , random SAMPLING , stratified random SAMPLING , power of the test, confidence interval that need to be specified for a SAMPLE size calculation and some TECHNIQUES for DETERMINATION of SAMPLE size , and also describes some SAMPLING methods such as purposive random SAMPLING , random SAMPLING , stratified random SAMPLING , systematic random SAMPLING and quota SAMPLING for specific research purposes.

pointed out that sample size determination is a difficult process to handle and requires the collaboration of a specialist who has good scientific knowledge in the art and practice of medical statistics. Techniques for estimating sample size and performing power analysis depend mainly on the design of the study and the main measure of the study.
