Wave data from two field stations and from the laboratory tests have been analyzed. The groupiness factor is used to categorize the wave data for the discussion of the correlation between the wave height and the wave energy. The result shows that the proportionality coefficient between the significant wave height and the square root of the wave energy is positively correlated to the groupiness factor and it is larger in shallow water than in deep water. The statistical theory overestimates the coefficient except for waves with large groupiness factor in shallow water.
