In scientific experiments, a dependent variable is the variable that is being measured or observed. It is the variable that is affected by the independent variable, which is the variable that is being manipulated or changed in the experiment. The dependent variable is the outcome or result of the experiment, and it is used to determine whether the independent variable had an effect on the system being studied. For example, in an experiment testing the effect of fertilizer on plant growth, the dependent variable would be the height or weight of the plants, as these are the variables being measured and observed.
