Question

What is an example of an independent variable?

Answer 1

An independent variable is a variable that is manipulated or changed in an experiment to observe its effect on a dependent variable. For example, in a study examining the effect of different amounts of sunlight on plant growth, the amount of sunlight that each plant receives would be the independent variable. Researchers might vary the sunlight exposure (e.g., 2 hours, 4 hours, 6 hours per day) to see how it impacts the growth of the plants, which would be the dependent variable.
