operational definition
A statement that describes how a particular variable is to be measured or how a term is to be defined is known as an operational definition. This definition specifies the procedures or criteria used to quantify or categorize the variable, ensuring clarity and consistency in research. For example, if measuring "anxiety," one might operationally define it as the score on a standardized anxiety questionnaire. This approach allows researchers to communicate their findings effectively and replicate studies.

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.
Declaration is a promise: 'I will define (or has defined) this variable/function somewhere else'.
