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 ...

Non-probability Sampling

2016
A sample is a subset of a population and we survey the units from the sample with the aim to learn about the entire population. However, the sampling theory was basically developed for probability sampling, where all units in the population have known and positive probabilities of inclusion. This definition implicitly involves randomization, which is a

Screening of Probability Samples

International Statistical Review / Revue Internationale de Statistique, 1984
A screening technique is proposed for increasing the efficiency of sampling plans through the use of a concomitant variable. A procedure for determining the optimum screening limits is discussed. The technique is reviewed under certain superpopulation models.
