This document discusses different types of graphs and tables used to represent data. It introduces bar graphs, line graphs, circle graphs, and pictographs for visualizing data, as well as frequency tables and line plots for organizing raw numbers. Bar graphs compare data using bar lengths. Line graphs show changes over time by connecting points. Circle graphs represent parts of data as percentages of a whole circle. Pictographs use pictures to compare amounts of data, similar to bar graphs. Frequency tables list how often each item occurs, while line plots show frequencies using X marks.

Types of graphs
- 1. Graphs and Tables During this unit you will learn about 4 types of Graphs: Bar graph Line graph Circle (Pie) graph Pictograph You will learn about 2 types of Tables: Frequency Table Line Plot
- 2. Frequency Table Data – information Frequency Table – lists the number of times each item occurs in a data set.
- 3. Line Plot Uses X marks to show Frequencies
- 4. Bar Graph A bar graph uses the lengths of bars to represent data. Bar graphs are used to compare data.
- 5. Line Graph A line graph uses points connected by a line to represent data. A line graph is used to show changes over time.
- 6. Circle Graph A circle graph represents data as part of circle. A circle graph is used to compare parts of data to the whole data.
- 7. Pictograph A pictograph uses pictures to represent data. It is similar to a bar graph because it compares data.
