This guide explores three essential types of graphs: line graphs, bar graphs, and pie graphs. Line graphs display changes in one group over time, often featuring multiple lines for comparison. The x-axis represents time, while the y-axis indicates the measured variable. Bar graphs allow for the comparison of several groups simultaneously, making it easier to see differences. Pie graphs illustrate how one group relates to the whole, providing a visual representation of proportions. Learn the significance and application of each graph type.
E N D
Line Graph • Shows change in one group over periods of time. • More than one line can be used on the same graph • X-Axis- horizontal, time • Y Axis- vertical, what is being measured
Bar Graph • Compares several groups at one time.
Pie Graph • Shows how 1 group compares to a whole group
