Answer:
True
Step-by-step 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.
