Operational definition
The term that describes a variable controlled by the experimenter is the "independent variable." This variable is manipulated to observe its effect on another variable, known as the dependent variable, which is measured in the experiment. By controlling the independent variable, the experimenter can establish cause-and-effect relationships in their research.

To measure a variable, you need to first define what you are trying to measure and then select an appropriate method or instrument to quantify it. This could involve using tools such as surveys, scales, observations, or sensors depending on the nature of the variable. Ensure that the measurement process is reliable, valid, and consistent to obtain accurate results.
The dependent variable is the outcome or response that is being measured in an experiment. It is what is affected by changes in the independent variable, which is the variable being manipulated. The dependent variable is dependent on the independent variable.
The variable that describes data using words or numerals as labels is called a categorical variable.
A controlled experiment involves manipulating one variable (independent variable) while keeping all other variables constant, in order to observe the effect on another variable (dependent variable). This allows researchers to determine a cause-and-effect relationship between the variables being studied.
