Collecting the Data 6. 5 1.1.1 Principles of Sampling A representative sample needs to have the same characteristics as the target population. Hence, the usual point of view is that the sample size is the determined function of variability, statistical method, power and difference sought. According to Uma Sekaran in Research Method for Business 4th Edition, Roscoe (1975) proposed the rules of thumb for determining sample size where sample size larger than 30 and less than 500 are appropriate for most research, and the minimum size of sample should be 30% of the population. n Introduction Mixed methods has emerged in the social and behavioral sciences during the past two decades, joining qualitative and quantitative methods of schol-arly inquiry as the "third research community" (Teddlie & Tashakkori, 2009 .
