An independent variable is a variable in an experiment or study that is manipulated or changed by the researcher to observe its effects on a dependent variable. It is considered the "cause" in a cause-and-effect relationship. The independent variable is not affected by other variables in the experiment; instead, it is used to test hypotheses and determine relationships between variables. For example, in a study examining the effect of different amounts of sunlight on plant growth, the amount of sunlight would be the independent variable.
