Making and Understanding Graphs

What is a graph? A graph is a “picture” of your data.

There are three types of graphs. Line graph Bar graph Pie chart

The Line Graph Used to track changes over time.

The Bar Graph Used to compare different groups.

The Bar Graph.

The Pie Chart Compare parts of a whole.

What information is needed to make a bar or line graph? A title A legend An X-axis

What information is needed to make a bar or line graph? A Y-axis The data

What information is needed to make a pie chart? A title A legend The data

The Title Gives a short explanation of what is in your graph.

The Legend It tells what each shaded area on the graph represents.

Y-Axis Runs vertically (up-and-down).

X-Axis Runs horizontal (flat).
