Terms and Conditions.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. DEFINITIONIn what follows, we offer some answers to these questions and relate them to a sequence of examples that provide an overview of current statistical practice.
