This document discusses key concepts in statistics including populations and samples, descriptive and inferential statistics, and methods for organizing and presenting quantitative data. It provides examples of how to construct frequency distributions, histograms, stem-and-leaf plots, and identifies ways that visual displays of data can be misleading if they distort relationships in the underlying data. The goal is to select appropriate methods for summarizing data and to be able to identify deceptions that can occur in visual representations of statistics.
