Types of variables

​Variables can be divided into 3 types:

1. Control variables: the one that's kept the same (unchanged)

2. Independent variables: The one that's being changed

3. Dependent variables: The one that's being measured

Some text here about the topic of discussion

When you plot a graph of your results, the independent variable always goes along the horizontal axis. The dependent variable always goes up the vertical axis.
