The factor that changes when the manipulated, or independent, variable is changed is known as the dependent variable. This variable is one of the two variables that are being investigated. When graphing the results of an experiment, the independent variable's values are placed on the x-axis of the graph and the values of the dependent variable are placed on the y-axis. An example of a manipulated variable and dependent variable relationship is seen in an investigation where the effect of temperature (manipulated) is seen on the amount of sugar that can be dissolved in water (dependent).
