1. Aim: How do scientists interpret data (Part 3)? Do Now: Copy the following: Line Graph - A graph that is used to display data that shows how one variable (dependent) changes in response to another (independent).

2. Why use a line graph? Line graphs show relationships. They are useful for sowing trends, or patterns in the data. They can also be used to make inferences and predictions about data that was not measured directly.

3. Tips for Creating Line Graphs Draw a horizontal (x) and vertical (y) axis on the graph paper. Label both axis. The x-axis should be labeled with the name of the independent variable, and the y- axis should be labeled with the dependent variable. Choose a scale for each axis. Each square of the graph paper should represent the same amount. Plot your data points. Connect each point. Write a title that clearly describes what is shown in the graph. The title should include the independent and dependent variables.
