# Line Graph on Paper

 How To Construct a Line Graph On Paper Step What To Do How To Do It 1 Identify the variables Independent Variable – (controlled by the experimenter) Goes on the X axis (horizontal) Should be on the left side of a data table Dependent Variable – (changes with the independent variable) Goes on the Y axis (vertical) Should be on the right side of a data table 2 Determine the variable range. Subtract the lowest data value from the highest data value. Do each variable separately. 3 Determine the scale of the graph. Determine a scale. (the numerical value for each square), that best fits the range of each variable. Spread the graph to use MOST of the available space. 4 Number and label each axis. This tells what data the lines on your graph represent. 5 Plot the data points. Plot each data value on the graph with a dot. You can put the data number by the dot, if it does not clutter your graph. 6 Draw the graph. Draw a curve or a line that best fits the data points. Most graphs of experimental data are not drawn as “connect-the-dots”. 7 Title the graph. Your title should clearly tell what the graph is about. If your graph has more than one set of data, provide a “key” to identify the different lines.
