Graphs

The results of an experiment are often used to plot a graph. A graph can be used to verify the relation between two variables and, at the same time, give an immediate impression of the precision of the results. When we plot a graph, the independent variable is plotted on the horizontal axis. (The independent variable is the cause and the dependent variable is the effect.)
