List and explain the 4 different types of variables and explain them.

Nominal, ordinal, interval and ratio.

Explanation:

I don't know how to explain them.

independent, dependent, control

Explanation:

The independent variable is the variable that you change. For example, if we were growing plants and wanted to see if more sun made them grow higher, you would change the amount of sun that each plant is exposed to.

The dependent variable is what you measure. This depends on the independent variable. So, in our plant experiment, the height of the plant is the dependent variable.

Control. The control is what stays the same. So in our plant experiment, the amount of water, type of plant, type of soil, and all of these things would stay the same to insure that the results are equal.
