In an experiment where Jackson is testing the effect of different amounts of sunlight on plant growth, what is the purpose of controlled variables?

• To ensure that both groups of plants receive the independent variable.

• To ensure that the results of the experiment are due to the independent variable.

• To measure the effects of the dependent variable.

• To gather information using senses.
