Two kinds of surface elevation data with a diverse form of spectrum are analyzed to investigate the effect of spectral form on a ratio of the surface elevation-based statistics to the spectrum-based statistics of wave height and period. One is generated by use of a Monte-Carlo simulation and the other is acquired from in-situ measurements. Main conclusions are 1) a proper evaluation for the parameter characterizing the spectral form requires a highly-resolved estimate of spectrum, 2) wave height ratio is most closely related to the spectral peakedness parameter Qp and each of the wave period ratios to the spectral width parameter v, and 3) the simulation-based ratio indicates an explicit dependency on double-peakedness of the spectrum, but the measurement-based ratio shows a weak dependency due to statistical variability.
