Please take a look at the following article: Teng et al - Video games and Aggression.pdf

The Independent Variable of the above article is playing violent video games. How is that operationalized?

		Having all participants sign an informed consent form.
		Playing a video game twice a week for 2 hours each time.
		Filling out the Buss-Perry Aggression Questionnaire (AQ).
		Finding that playing violent video games leads to an increase in aggressive attitudes.

Answer 1

Playing a video game twice a week for 2 hours each time is operationalized properly because the operationalizing process would include definite numbers and defined people who would be used in the process. Two weeks and two hours are very well defined rather than saying sometimes or frequently etc. When it comes to operationalization, only practical terms as accepted and not abstract terms. It refers to how a researcher would measure the impact of an independent variable to support the thesis statement.
