A researcher who studies insomnia is analyzing data from a recent clinical trial. The trial involved two independent variables - taking either a placebo or melatonin pill, and participation in either a nightly meditation practice or sleep as usual. She then measured hours of uninterrupted sleep. (Let's say for this example that they stopped measuring hours of sleep as soon as participants woke up, even in the middle of the night)
