Use the averages of your data to make at least one of the following types of graphs as follows:

• Title your graph (Independent Variable vs. Average Dependent Variable).
• Label the horizontal (X) axis with the independent variable. Also label the horizontal (X) axis with what changes were made to the independent variable to test the hypothesis.
• Label the vertical (Y) axis with the average of the dependent variable and a numerical scale that corresponds to the dependent variable data measurements.

• NOTE: For most line graphs, draw a smooth line through the data points to show the best straight line pattern or single smooth curve pattern. DO NOT "connect the dots".

examples:

Titles and labels for

bar graphs and lines graphs in general.

Line graphs are appropriate when

the independent variable is numerical.

Bar graphs are appropriate when

the independent variable is not numerical.

Pie graphs are appropriate for showing percentages

when the independent variable is not numerical.
