[45 ] Van Statistical inferences can be drawn from the zero-stage of a snowball sample, assuming that proba- bility methods of selection were used. Samples drawn at s1 weights for the initial snowball sampling waves. 1 Introduction. Standard sampling and estimation techniques require the sample selection to be done. Sampling these populations is difficult because standard statistical sampling methods require a list of population members (i.e., a “sampling frame”) from which the The methods of statistical inference applied to the data obtained from an s stage k name snowball sample will of course depend on the kind of random sample. control study that used the snowball sampling method based on friendship for the selection of cases and controls. Methods. The cases selected for the study
Chapter 4 Stratified Sampling An important objective in any estimation problem is to obtain an estimator of a population parameter which can take care of the salient features of the population. If the population is homogeneous with respect to the characteristic under study, then the method of simple random sampling will yield a SAMPLING Nonprobability Sampling !

Jul 15, 2005 · Snowball sampling is a well‐known, nonprobability method of survey sample selection that is commonly used to locate hidden populations. This method relies on referrals from initially sampled respondents to other persons believed to have the characteristic of interest. ISSN Print: Pros and cons of different sampling techniques Pros and cons of different sampling techniques Gaganpreet Sharma Abstract In the field of research different sampling technique are used for different fields. It is very essential to choose the adequate technique of sampling. In this paper first we clarify the proper meaning of sampling.

culties of using snowball sampling tech-niques. Snowball Sampling Snowball sampling may simply be defined as: A technique for finding research subjects. One subject gives the researcher the name of another subject, who in turn provides the name of a third, and so on (Vogt, 1999). This strategy can be viewed as a response to
