PROBABILITY SAMPLE

Sociologyindex, Sociology Books 2011

Probability sample in social science research is a sample drawn from a population using methods which ensure random selection; each member of the population must have an equal probability of being drawn.

Probability and sampling
J S Bulman & J F Osborn
British Dental Journal 166, 132 - 135 (1989)
Abstract: The concept of probability is introduced, and the role of probability distributions in statistical theory is discussed, with particular reference to the Normal distribution and its characteristics. Sampling and sampling variation are described, together with sampling error, the standard error of the mean, and confidence intervals for determining the likely magnitude of a population mean.

Probability Sample Designs that Impose Models on Survey Data

Abstract: For a substantial class of sampling problems, the sample design and the characteristics of the population being sampled, not only provide the probabilities of selection but also impose a regression model on the sample data.
For many of these sampling problems this duality is an academic curiosity but there are some designs where inference based on the design and the probabilities of selection can be unacceptably inefficient.
For such designs, the model provides a backup, a Best Linear Unbiased Estimator (BLUE), and avoids the inefficiencies of the Horvitz-Thompson (HT) based estimation methodologies.

Survey non-response in a national area probability sample as a dimension of survey quality; an analysis of community characteristics
Kim, Jibum. and Sokolowski, John
Paper presented at the annual meeting of the American Association
Abstract: Most area probability surveys collect little to no information about non-respondents. This paper aims to explore the community characteristics of survey non-respondents in a nation area probability survey. Data selected for use is obtained from the 2004 General Social Survey, an area probability sample of 6260 housing units. Results from the survey are nationally representative of English speaking residents. We expect that wealthy and racially segregated areas are more likely to have high non-response rates. This paper examines community characteristics in relation to survey non-response and proposes ways to improve response rates among high non-response communities in national area probability surveys.
