Let’s create a bar graph with this format. 0011 0010 1010 1101 0001 0100 1011 1 2 4 How to set up your graph! 0011 0010 1010 1101 0001 0100 1011 1 Y Axis (This is for your dependent variable) 2 4 How to set up your graph! 0011 0010 1010 1101 0001 0100 1011 1 2 4 X Axis (This is for your independent variable) T.A.I.L.S. Graphing System 0011 0010 1010 1101 0001 0100 1011 You will have a wonderful graph if you follow the T.A.I.L.S. system. It will help you set up and label your graph properly.

T – Title Choose a scale that lets you make the graph as large as possible for your paper and data.

The interval is just as important as the scale. Choose an interval that lets you make the graph as large as possible for your paper and data.
