True or False: Graphs provide a good visual representation of the relationships between the factors investigated in an experiment?

True

Explanation:

Yes, the graph provides a good visual representation of the relationship between the factors being investigated when there are only two variables being studied at a time. Sometimes a third variable is represented on a negative y-axis which plays a minor role in any one of the factors that may be conveniently represented. Since we can draw only 2-dimensional diagrams on a paper, therefore, graphs are restricted to a couple of variables. The independent variable is usually represented on the x-axis and the dependent variable is represented on the y-axis. Graphs tell us the pattern of variation of a quantity with respect to another.
