In an experiment, the independent variable is the one that is manipulated or changed by the researcher to observe its effects on another variable. In this case, Professor Brown is changing the children's diets (high-carbohydrate diets) to see its effect on another variable, which is the children's activity levels. The dependent variable is the outcome or the variable that is being measured or observed to see how it is influenced by changes in the independent variable. Here, the children's activity levels are being measured to see how they are affected by the changes in their diets. Therefore, the children's diets are the independent variable, and the children's activity levels are the dependent variable.
