What is the dependent variable in a plant growth experiment

You will use two variables in the experiment: seed variety and amount of water. These variables are the factors in the experiment. The seed factor will be three varieties of the same type of plant, and its levels will be denoted by 1, 2, and 3.

The dependent variable is the mean height of seedlings. Control variables are the number of seeds on each dish, how much they are spread out, the volume of water the seedlings are given, the temperature they are kept at.

For this question, the amount that the plants grow is what is being measured, so this is the dependent variable. The dependent variable depends on the independent variable. The amount that the plants grow depends on the amount of sun they get.

A dependent variable is the variable that changes as a result of the independent variable manipulation. It's the outcome you're interested in measuring, and it “depends” on your independent variable. In statistics, dependent variables are also called: Response variables (they respond to a change in another variable)
