CHAPTER 4 Data, Statistics, and Probability Lesson 1: Tables and Pictographs Key Ideas Tables and graphs are often used to display data. Always read all labels to understand what data are presented in the table or graph. If symbols are used in a graph, a key will explain what each symbol represents. Data are facts and information. By analyzing data, we can make predictions, draw conclusions, and solve problems. To be useful, data must be organized in some way. A table organizes data in columns and rows. The labels on the table will help you understand what the data mean. Example 1: The table below shows population figures for selected counties in 2000 and 2010 and the land area in square miles for each county. County 2000 Pop. 2010 Pop. Land Area in sq. mi.
