Operational Hypothesis: States how the variables being studied will be observed, manipulated and measured, and outlines the population from which the sample has been selected.
Example: Study on noise and problem solving ability
Operational Hypothesis:
‘Year 11 VCE students who continuously listen to loud rock music when solving previously unseen written problems will solve fewer problems during a one hour session than do Year 11 VCE students who do not listen to loud rock music ‘
This operational hypothesis contains all of the information required:
Variables being studied: (IV: Listening/not listening to music during a one hour session) (DV: Amount of unseen writing problems solved)
Population: Year 11 VCE students
How the experiment will be conducted: One group will listen to loud rock music when problem solving (experimental group) and another group will not listen to loud rock music when problem solving (control group).
