Variables must be operationally defined to ensure clarity and consistency in research. An operational definition specifies how a variable will be measured or identified, allowing for reproducibility and comparability across studies. This precision helps researchers avoid ambiguity and ensures that the findings can be understood and interpreted correctly by others in the field. Ultimately, operational definitions enhance the validity and reliability of the research outcomes.

The variable sense of humor can be operationally defined by using standardized humor assessment tools, such as humor appreciation questionnaires or humor response inventory scales, to measure individuals' responses to humor stimuli. This operational definition can quantify participants' subjective ratings of comedic content, their laughter intensity, and their frequency of making jokes or humorous comments in social interactions.
The four defined thermodynamic variables (pressure, volume, temperature, and number of particles) are typically sufficient to fully describe the state of a system and predict its behavior. Any additional variables would be redundant or could be expressed in terms of the defined variables. These four variables form the foundation for understanding and applying the laws of thermodynamics.
Quiz and exam scores are discrete variables because they are defined as one exact number.
all variables have been carefully operationalised

System environment variables
Environment Variables: Sometimes called special shell variables, keyword variables, predefined shell variables, or standard shell variables, they are used to tailor the operating environment to suit your needs. Examples include PATH, TERM, HOME, and MAIL.User-defined Variables: These are variables that you create yourself.Positional Parameters: These are used by the shell to store the values of command-line arguments
The Math class has public variables - defined as final, of course - for the mathematical constants PI and E.
