Controlled variable: the height of the slope, the car, the unit of time e.g. minutes and the length of the slope. What you can decide to change in an experiment.
What’s an example of a control variable?

One group, the experimental group would receive the drug and the other would receive a placebo. The group that received the placebo is the control group.

What is a control variable in sociology?
Control Variable: A variable that is held constant so that the effect of a third variable (which you are interested in) on the dependent variable can be observed more clearly. Generally, you control by selecting only individuals who share in common the variable you are controlling for (age, gender, etc.)
What are positive controls?
A positive control group is a control group that is not exposed to the experimental treatment but that is exposed to some other treatment that is known to produce the expected effect. These sorts of controls are particularly useful for validating the experimental procedure.

Examples of Controlled Variables Temperature is a common type of controlled variable. If a temperature is held constant during an experiment, it is controlled. Other examples of controlled variables could be an amount of light, using the same type of glassware, constant humidity, or duration of an experiment.
