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...

متن کاملAccessing 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...
متن کاملA Snowball Sampling Approach for Studying Digital Minority Languages
This thesis discusses the methods used to assess the linguistic diversity of the internet. I critique the current literature on internet language diversity, arguing that existing methods-which aggregate textual data from many languages, to the exclusion of video and audio data-are unsuited to the study of minority languages. To address these shortcomings, I propose a snowball sampling approach ...
متن کاملConditional estimation of exponential random graph models from snowball sampling designs
A complete survey of a network in a large population may be prohibitively difficult and costly. So it is important to estimate models for networks using data from various network sampling designs, such as link-tracing designs. We focus here on snowball sampling designs, designs in which the members of an initial sample of network members are asked to nominate their network partners, their netwo...
