Comparision of Snowball Sampling and Sequential Sampling Technique

Representing against population with a subset of it is termed as sampling. Sampling can either be statistical or non-statistical. In statistical sampling (probability sampling technique) calculating the probability of getting any particular sample is possible. It is scientific and every element stands an equal chance of being selected. In statistical sampling, workforce, time and money highly l...

Sequential Sampling Plan with Fuzzy Parameters

In this paper a new sequential sampling plan is introduced in which the acceptable quality level (AQL) and the lot tolerance percent defective (LTPD) are a fuzzy number. This plan is well defined, since, if the parameters are crisp, it changes to a classical plan. For such a plan, a particular table of rejection and acceptance is calculated and compared with the classical one. Keywords : St...

Accessing Hidden and Hard-to-reach Populations: Snowball Research Strategies Snowball Sampling

Rowland Atkinson and John Flint are researchers at the Department of Urban Studies, University of Glasgow. Both have an interest in the spatial distribution and experience of social exclusion and have been commissioned to devise a methodology for tracing residents who leave regeneration areas in Scotland. •In its simplest formulation snowball sampling consists of identifying respondents who are...
