What is an example if an independent variable?

An example of an independent variable is the amount of sunlight a plant receives in an experiment measuring its growth. In this scenario, the researcher can manipulate the amount of sunlight (e.g., full sun, partial shade, complete shade) to observe its effect on the plant's height, which serves as the dependent variable. By varying the independent variable, the researcher can draw conclusions about the relationship between sunlight exposure and plant growth.
