Creating an operational Hypothesis for Research
Methods example 1
I want to test the effect of Smoking Marijuana on Driving Performance.
Variables that need to be operationalised
Smoking Marijuana – smoking one joint containing 500 milligrams of pure
marijuana (not mixed with tobacco) 20 minutes before taking a driving test
Driving Performance - % score on VIC Roads, “Are you Road Ready?”
It is hypothesized that participants who have smoked marijuana (smoking one
joint containing 500 milligrams of pure marijuana 20 minutes before taking a
driving test) will perform worse on a driving test (obtain a lower % score on
the VIC Roads “Are you Road Ready?” driving simulator) compared to
participants who have not smoked marijuana.
