inferential statistics

a broad class of statistical techniques that allow inferences about characteristics of a population to be drawn from a sample of data from that population while controlling (at least partially) the extent to which errors of inference may be made. These techniques include approaches for testing hypotheses, estimating the value of parameters, and selecting among a set of competing models. Also called inductive statistics. Compare descriptive statistics.
