The independent variable in an experiment is the factor that the gardener manipulates or changes to observe its effect on other factors. In this case, the independent variable would be the amount of light each plant receives. This is because the gardener can control and vary the amount of light, and then measure how it affects the other variables, such as the average circumference of each plant’s fruit, the number of fruit per plant, or the height of each plant.
