Abstract Some normal A-type main sequence stars appear to have surface abundances like those of metallic lined Am-type stars. In this study, we investigate normal and metallic lined A stars to understand the details of their optical region abundances via statistical techniques for 13 elements (C, O, Mg, Si, Ca, Sc, Ti, Cr, Fe, Ni, Sr, Y, Ba) abundances determined by high resolution spectral data from DAO (Dominion Astrophysical Observatory) by Yüce ve Adelman (2014). With these data, correlation coefficients of 12 elements were calculated against their [Fe/H] abundances. As a result of regression analysis, the relationship of 12 elements with [Fe/H] abundance was determined. The results revealed that normal A-type stars differ from Am-type stars in terms of [Fe/H] abundance.
