PLES How do you actually acquire the sample? Ideally, take all the sites in the sample universe, give each one a number, and randomly select a portion and examine those sites. Random sample, a sample drawn from a statistical population such that every member of the population has an equal chance of being included in the sample.
Sample fraction, the percentage of the sample universe that is surveyed. Areas with variability in archeological remains require larger sample fractions than do areas of low variability. Sample units, survey units of a standard size and shape, determined by the research question and practical considerations, used to obtain the sample.
