Document Summary
Sampling: non-probability sampling any technique in which samples are selected without resort to. Probability selection (based on probability theory: probability sampling: a general term for samples selected in accord with probability theory, typically involving some random-selection mechanism. Types of non-probability sampling: convenience or accidental" sampling, purposive sampling, snowball sampling, quota sampling. Probability theory: the estimation of error in representativeness of a sample: probability theory allows a researcher to describe a population, based on a sample drawn from it; and to estimate the degree of error in their estimates . Probability sampling and epsm: basic principle of probability sampling -random selection and epsm. Types of probability sampling designs: simple random sampling, systematic sampling, stratified sampling, cluster sampling. Systematic sampling: a type of probability sampling in which at some specified interval (every kth element) an element in a population is selected for inclusion in the sample .
