In most academic and business studies‚ KMO & Bartlett’s test play an important role for accepting the sample adequacy. While the KMO ranges from 0 to 1‚ the world-over accepted index is over 0.6. In our research‚KMO measure of sampling adequacy is 0.799 which is in acceptable range. Bartlett test of Sphericity comes out to be significant. Values in the table indicate that data collected from the survey are suitable and reliable
