In addition, authors contend in the case where a study involves large-group design there is a need to apply multifaceted approach by taking average (Miller, Besser & Vigna, 2011). This is to aggregate all findings from other researches with the intention of obtaining exact results, which is extremely hard if one utilizes one method approach. Aggregation also includes taking data of diverse and numerous subjects with the intention of producing a group mean (Miller, Besser & Vigna, 2011). Contrary to single case researchers, whose intention encompasses addressing only external validity of a study; multifaceted approach normally takes in a wide varied of replication to exhibit all essential facts. This is evident in Miller, Besser & Vigna (2011) study that extends over a period of five years. Hence, allowing a large study examined in a single and small scope though its approach is multifaceted besides having replication of numerous researches and subjects (Miller, Besser & Vigna, 2011).
In this article, the author contends adopting of mixed methods approach plays a significant role in advancing beyond unclear hypothesis; hence ensure effective understanding of the highlighted aspects in a given study. This is especially in studies that involve innovation whose relaying of ideas entails to win the acceptance of the users (Wu, 2012). Wu utilized a mixed method in his research mainly because this mode of research ensures the researcher learn issues from a wider a scope. Mixed method approach utilizes both qualitative and quantitative methods of research, which in the end enables Wu effectively, evaluate all aspects concerning the subject of research (Wu 2012). According to Wu, mixed method enables a research to shift from unclear state of data or study to usefulness” and “ease of use”, which is essential in understanding varied aspects
