Experiments aim to measure the effect which one or more independent variables have on a dependent variable. The aim is to isolate and measure as precisely as possible the exact effect independent variables have on dependent variables
For example, if you grow tomato plants as a hobby and wanted to find out the effect which the amount of water, the temperature, and the amount of light has on the amount of tomatoes each plant produces you could design a series of experiments in which you varied the amount of light etc. and then measure the effects on the amount of fruit produced.
In the above example, the amount of tomatoes is known as the dependent variable and the water, the temperature and the amount of light are the independent variables.
Experiments typically start off with a hypothesis which is a theory or explanation made on the basis of limited evidence…
