A variable is a category or characteristic that’s measured in an equation or experiment. An independent variable is a variable that is changed in an experiment to produce a result. Look at other experiments for examples and identify different types of independent variables. Doing this helps ensure that the experiments know exactly what they are looking at or manipulating, allowing them to measure it and determine if it is the IV that is causing changes in the DV. In an experiment, some volunteers receive the new treatment, another group receives a different treatment, and a third group receives no treatment. A researcher wants to determine if the color of an office has any effect on worker productivity.
