Statistics and Sampling Distributions 1.1 Introduction Statistics is closely related to probability theory, but the two elds have entirely di erent goals. Recall, from Stat 401, that a typical probability problem starts with some assumptions about the distribution of a random variable (e.g., that it’s binomial), and the objective is and in the proper selection of statistical analyses for experimentally acquired data. John L. Gill [1] states: “…statistical analysis too often has meant the manipulation of ambiguous data by means of dubious methods to solve a problem that has not been defined.” The purpose of this article is to provide readers with definitions and examplesReport a problem.
