Surveys have shown radio-loud (RL) quasars constitute $10 \%$-$15 \%$ of the total quasar population and rest are radio-quiet (RQ). However, it is unknown if this radio-loud fraction (RLF) (RL quasars/Total quasars) remains consistent among different parameter spaces. This study shows that RLF increases for increasing full width half maximum (FWHM) velocity of H$\beta$ broad emission line. Our data has been obtained from \cite{shen} catalogue. Our sample consists of quasars with magnitude less than 19.1 and limited upto redshift 0.75. We are getting RLF for FWHM of H$\beta$ broad emission line greater than 15000km/s is 0.577. To analyse the reason, in this preliminary study we compare various properties like bolometric and 5100\.{A} luminosities, BH mass and accretion rate of RL and RQ quasars sample which have FWHM of H$\beta$ broad emission line greater than 15000km/s (High Broad Line or HBL) with which have FWHM of H$\beta$ emission line less than 2500km/s (Low Broad Line or LBL) and from the distributions we can conclude for all the properties in HBL, RQ and RL are peaking separately whereas for LBL the peaks are almost indistinguishable. Then we compare our result with other literature and by crossmatching our sample with VLBI we have shown that some objects from our sample are not following the graph of logR vs FWHM plot from Wills and Browne 1986 where R is the ratio of radio core flux density with the extended radio lobe flux density. We are also getting 5 objects which are behaving exceptionally from logRv vs FWHM plot.Where logRv is the ratio of radio and optical luminosity at rest frame.
