In mathematical modeling, statistical modeling, and experimental sciences, there are independent and dependent variables.
- Dependent variables get their name because, during an experiment, their values are examined under the assumption or requirement that they are dependent on the values of other variables due to some law or rule (for example, a mathematical function).
- In the context of the experiment in question, independent variables are those that are not perceived as dependent on any other factors.
A body camera or wearable camera is a wearable audio, video, or photographic recording system used to capture events that law enforcement officers are involved in. On an officer's uniform, they are normally worn on the torso.

These tools are widely thought to accomplish a number of goals, including lowering police use-of-force and complaints against officers, improving police legitimacy and transparency, raising prosecution rates, and enhancing police evidence collection.
- Because of all the exposure, many people now believe that cameras can fundamentally alter "flawed" police procedures.
Thus this is the answer of dependent and independent variable and police worn cameras.
