Statistics is not an exact science. After all, the whole point of statistics is to make generalizations about the population under study using a portion of the population’s data. Therefore the notions of sampling error, bias, estimators, degrees of freedom, and the central limit theorem become essential to understand if you are to design, develop, and carry out any study that involves the collection of data. This module introduces you to these concepts, along with their practical use in confidence intervals and with the t‐distribution.
