This paper attempts to propose general correlation between shear wave velocity and standard penetration resistance based on empirical research equations which had been established worldwide. It first reviews earlier development and current advancement of previous related studies. Short reviews had revealed that previous investigations are all site dependant studies which tend to be independent from other researchers. Although numerous researchers had studied the correlation regression through empirical data, there is no concrete evidence to plot the range boundary of the regression correlations. Most researchers are in consensus to use a power-law form in describing the relationship. Noticed that there is still no concrete evidence to plot the boundary range of the regression correlations, it is thus mandatory to carry out statistical analysis to draw such conclusion. The controversy and confusion of this state require more in-depth studies to confirm the finding significance. Based on earlier published correlations, statistical analysis was carried out to generate correlation which is applicable to all soil types. New correlations are proposed by combining 27 published correlations in two ways, (i) without outliner and (ii) with outliner. The correlation with outliner data gives higher correlation coefficient and lower percentage of error. This study shows an advancement to incorporate all earlier research findings to generate correlations which are applicable to all soil types globally.
