A researcher conducts a 2-year longitudinal study of a sample of overweight Americans. Which correlation coefficient is she MOST likely to find between the number of hours the participants say they sleep each night and the amount of weight they gain over the 2-year study period?

Answer :

The most likely corelation between the number of hours of sleep and the amount of weight gain is that when they sleep less hours, they gain more weight. This happens, because when people are sleep deprived and are running on low energy, they tend to go after comfort foods, like a bag of potato chips or some cookies. Plus sleep is important to maintain a good metabolism.
