The document provides instructions for creating bar and line graphs, including how to label the axes, choose an appropriate scale and interval, and add a title. It explains that the dependent variable goes on the y-axis and independent variable on the x-axis. Bar graphs are used to compare categorical data, while line graphs show relationships between variables and trends over time. Examples of properly formatted bar and line graphs are also included.

1. How to Create Bar and Line Graphs

2. Draw the Axes

3. Identify the Axes Y- Axis X- Axis

4. Identify the Axes Y- Axis X- Axis Dependent Variable (what is observed and measured) Independent Variable (what is changed by the scientist)

11. Intervals The interval for the Y-axis is 20. The X-axis does not have numerical data and does not need an interval.

13. Labels DV label IV label

15. TAILS Title: Includes both variables Axis: IV on X-axis and DV on Y-axis Interval: The interval (4) is appropriate for this scale. Label : Both axes are labeled. Scale: Min and max values are appropriate.
