The idea that "there is no difference" between performance on experimental
and control conditions is often called "the null hypothesis".
- Do wearable computers help people keep appointments?
How well do people keep appointments without wearables?
They keep appointments about as well either way.
- Do subliminal cues improve memory performance?
How well do people do on the memory task without subliminal cues?
The subliminal cues have no effect on the memory task.
In research, one frequently hopes to reject the null
hypothesis.
