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.
