**2.2 Research design**

We employed the mixed method approach of research investigation. The study further used the sequential explanatory mixed methods design. This approach is supported and accepted by the pragmatic paradigm [54]. This was to allow the initial quantitative data results to be explained further with the qualitative data. This triangulation of several methods provides the strengths and weaknesses of individual methods [55, 56]. We used questionnaire surveys and interview guides for primary data collection purposes. Secondary sources used included books, journals, articles, and some scholarly internet sites, such as jstor.org, database, and Google advanced search. The use of secondary data was to help us gain an initial insight into the research problem.
