Interpreting Graphs 1
Graphs show the relationship between two variables. The independent variable is the one the investigator changes. It is plotted on the x-axis (horizontal).
The dependent variable is the one that is measured. It is plotted on the y-axis (vertical).
Each axis must have a label and units, for example "Temperature / °C". The scale should be even and use more than half of the grid.
