Frequently asked questions
Statistics is an important decision-making tool in the everyday world. It represents the branch of applied mathematics concerned with collecting, analyzing, interpreting, and presenting empirical data. Empirical data involves the facts and figures assembled and used to answer questions about a group. Statistics relies on the theory of mathematical and computational tools to infer conclusions from qualitative and quantitative data. Qualitative data provides names or labels for categories of similar items—quantitative data measures how much of something there is. Characteristics of individual members of a group are the variables of the study. Statistical methods focus on concluding large groups, called populations, based on information obtained from observations made in small samples from that population.
