  • nonprobability
  • In nonprobability sampling, members are selected from the  population in some nonrandom manner.
  • convenience sampling,
  • In nonprobability sampling, the degree to  which the sample differs from the population remains  unknown.
  • Convenience sampling is used in  exploratory research where the researcher is interested  in getting an inexpensive approximation of the truth. As  the name implies, the sample is selected because they are  convenient. This nonprobability method is often used  during preliminary research efforts to get a gross  estimate of the results, without incurring the cost or  time required to select a random sample.

  The advantage of probability sampling is that sampling error can be calculated. Sampling error is the degree to which a sample might differ from the population. When inferring to the population, results are reported plus or minus the sampling error. In no

  • Stratified sampling is commonly used  probability method that is superior to random sampling  because it reduces sampling error. A stratum is a subset  of the population that share at least one common  characteristic. Examples of stratums might be males and females, or managers and non-managers. The researcher first identifies the  relevant stratums and their actual representation in the  population. Random sampling is then used to select  a sufficient number of subjects from each stratum. "Sufficient" refers to a sample size large enough for us to be reasonably confident that the stratum represents the   population. Stratified sampling is often used when one or  more of the stratums in the population have a low  incidence relative to the other stratums.
