Resources > Resource Packs > Sampling

Sampling and sample size are crucial issues in pieces of quantitative research, which seek to make statistically based generalisations from the study results to the wider world. To generalise in this way, it is essential that both the sampling method used and the sample size are appropriate, such that the results are representative, and that the statistics can discern associations or differences within the results of a study.

The first part of this pack looks at how to gather a "representative" sample which gives a study external validity and permits valid generalisation. While the second half of the pack considers the issues of sample size, and how to calculate an adequate size for a study sample.

This resource packs suggests further reading and resources as well as supplying a glossary of terms.
