Data Analysis

The goal of data analysis is to understand data well enough to describe past and present trends, predict future events with some certainty, and thereby make better decisions. In this limited review of data analysis, we begin with tools for describing data; follow with tools for understanding counting and probability; review the concepts of distributions of data, random variables, and probability distributions; and end with examples of interpreting data.
