Sample Size One of the fundamental tasks in qualitative research, other than the selection of a research topic, is to produce credible research by obtaining an appropriate sample. This is to ensure that there are enough facts for possible research and justifications of the qualitative research’s conclusions (Marshall, Cardon, Poddar, &Fontenot, 2013). According to Marshall, Cardon, Poddar, and Fontenot (2013), qualitative researchers rarely justify the sample sizes of qualitative interviews. Further, the available qualitative research methodologies provide few concrete guidelines for estimating adequate sample sizes. This is particularly evident in information systems (IS) research studies (Marshall, Cardon, Poddar, & Fontenot, 2013), despite the plethora of information systems (IS) qualitative research information that exists. Indeed, according to Sarker, Xiao and Beaulieu (2013), up to the mid-1990, a significant amount of mainstream IS scholars, particularly those in North American and Asia, research was assumed to be quantitative, and studies not using the accepted quantitative methods were excluded from the definition of research itself. Qualitative research uses purposeful sampling instead of drawing a random sample and addressing the assumptions of statistical analysis techniques. Hanson, Balmer, and Giardino (2011) noted that the research chooses a sample of participants or documents to accomplish a particular purpose and to gain the insight most applicable to the research question. As the study proceeds, the qualitative researcher may identify additional participants or documents likely to confirm or challenge emerging insights in an attempt to build deeper understanding and to clarify themes (Hanson, Balmer, &... ... middle of paper ... ...ew of qualitative interviews in is research.

  • Thematic Analysis Essay

    1280 Words  | 3 Pages

    Thematic analysis is espoused to be the foundational approach to qualitative analysis and methods (Saunders et al., 2016 as stated in Braun and Clarke, 2006: 78) and it is a useful method used to identify and analyse the order and patterns of qualitative data (Attride-Stirling, 2001). Qualitative research method depicts the correlation that exists between data and events, creating the pictorial representation of what one thinks a given data says (Saunders et al., 2016). They also opined that, qualitative data analysis is cogent, interactive and iterative. Also, Joana and Jill (2011) and Saunders et al (2016) postulate that, qualitative research brings meanings from words and images as opposed to numbers. However, despite its robustness and rigour of its application, it is skewed more to the interpretivist ideologies since researchers draw conclusion from participants and the hypothesis being forecasted (Joana and Jill, 2011; Saunders et al., 2016).

    Qualitative research is an approach that attempts to situate an activity that locates the observer in the world by providing the study to occur in their natural setting and by attempting to make sense of, or interpret information (Denzin and Lincoln, 2005). A characteristic of qualitative research is to use a variety of empirical materials such as personal experience, interviews, and questionnaires. It is imperative to understand the task at hand and how to fully carry out the study when using a qualitative research approach in order to find out the information needed. One view of qualitative research is it involves examining individual’s experiences and documenting those experiences in detail (Jones, 2011). By documenting these observations the researcher is ensuring validity in his or her data and giving the correct creditability to those who participated in the study.

  • Background: The Service Quality Models

    1550 Words  | 4 Pages

    The context of service quality has not been perceived uniformly. Cullen (2001) for instance portrayed two sets of quality context: objective, and perceived quality; the first focuses on the standards and guidelines being set up by professional bodies, while the second pertains to customers' perceptions. Similarly, Gronroos (1984) abstracted the service quality into technical and functional. By and large, literature on service quality has been lined up behind the latest category while maintained a level of disintegration with the first. On the other hand, scholars have endeavored to improve service quality. Their models that conceptualize service quality improvement included the disconfirmation, perceived quality, SERVQUAL, and Six Sigma (Kasper, Helsdingen, and Gabbott, 2006:183). Additionally, Ahmed and Rafiq (2002:13) spelled out two other models namely Berry's model and Grönrros' model, but placed them within the context of the internal marketing theory. However, the preceding models perceived service quality from a narrow perspective; none have had a holistic view of quality. This explains the inconsistency in conceptualizing service quality where the perceived service quality endured to measure customers' satisfaction in particular.
