This session investigates the nature of data and its potential sources of variation. Variables, bias, and random sampling are introduced. View Transcript.A sample is defined as a set of selected individuals, items, or data taken from a population of interest. A characteristic (usually numeric) that describes a sample is referred to as a sample statistic. NOTE: Inferential statistics are used to help the researcher infer how well statistics in a sample reflect parameters in a population.
