Operational definitions are also used to define system states in terms of a specific, publicly accessible process of preparation or validation testing. For example, 100 degrees Celsius may be operationally defined as the process of heating water at sea level until it is observed to boil.
What is the operational definition of psychological?
The “operational” part means giving the meaning of something as it’s being used in a particular study. So in psychology, an operational definition means defining the variable as it exists in the present study.
What are operational definitions of variables in psychology?
Operational variables (or operationalizing definitions) refer to how you will define and measure a specific variable as it is used in your study. This enables another psychologist to replicate your research and is essential in establishing reliability (achieving consistency in the results).
What is an example of an operational definition of a dependent variable?
The dependent variable is the variable that is being measured or tested in an experiment. 1 For example, in a study looking at how tutoring impacts test scores, the dependent variable would be the participants’ test scores since that is what is being measured.

Test: A specific procedure for measuring a characteristic. Decision: The determination as to whether the test results show that the characteristic meets the criteria.
