For example if we want to explore whether high concentrations of vehicle exhaust impact incidence of asthma in children vehicle exhaust is the independent variable while asthma is the dependent variable. Dependent Variables on a Graph. Here are several examples of independent and dependent variables in experiments. Knowing the independent variable definition and dependent variable definition is key to understanding how experiments work.

A Dependent variable is what happens as a result of the independent variable. There are no. The dependent variable sometimes known as the responding variable is what is being studied and measured in the experiment. Dependent and independent variables. While an experiment may have multiple dependent variables it is often wisest to focus the experiment on one dependent variable so that the relationship between it and the independent variable can be clearly isolated. The following scatterplot shows the.
