All three studies were reviewed and approved by the FHI 360 Protection of Human Subjects Committee; the study which produced Dataset 3 was also reviewed and approved by local IRBs in Kenya and South Africa. Themes get identified by physically sorting the examples into piles of similar meaning. The researcher closely examines the data to identify common themes topics, ideas and patterns of meaning that come up repeatedly. That is while ordinal data is sometimes classified under quantitative data. Dataset 2. Following a review of the empirical research on data saturation and sample size estimation in qualitative research, we propose an alternative way to evaluate saturation that overcomes the shortcomings and challenges associated with existing methods identified in our review. Interested in ChatGPT For 1-on-1 Interviews? The lower the new information threshold, the less likely an important number of themes may remain undiscovered in later interviews if data collection stops when the threshold is reached. Caulfield, J. should I not use TA? Researchers often use data-analysis software for analyzing large amounts of qualitative data. Thematic analysis can be used to analyze quantitative data sets in order to identify patterns and themes. No, Is the Subject Area "Metaanalysis" applicable to this article? Some types of research questions you might use thematic analysis to answer: The results for Dataset 2 were nearly identical to Dataset 1 (Table 3). For example, Onwuegbuzie and Johnson (2021) note "data analysis in mixed methods research [can be]the most difficult step of the mixed methods research process" (p. 1) and there is a "lack of methodological guidance in the extant literature on these topics" (p. 16). This renders a quotient of 11%, still not below our 5% threshold. Interested in What Is A Acoustic Model In Speech Recognition? Tran and colleagues [24] accurately point out that determining the point of saturation is a difficult endeavor, because researchers have information on only what they have found (pg. Height in feet, age in years, and weight in pounds are examples of quantitative data. What (exactly) is quantitative data analysis? It is usually applied to a set of texts, such as an interview or transcripts. The new information threshold selected affects the point at which saturation is indicated, as one would expect. For any method of assessing saturation, including ours, researchers need to decide at which level they will identify and include themes/codes. We use cookies to ensure that we give you the best experience on our website. And, like power calculations, they are moot once data collection begins. Your email address will not be published. Yes Yes, thematic analysis can be used in quantitative research. Qualitative data of mixed method requires thematic analysis in one way or another. What a quantitative researcher accepts, for example, as a large enough effect size or a small enough p-value is a subjective determination and based on convention in a particular field of study. Scribbr. The approach to analyze data in qualitative research cannot be the same as in the quantitative research. To approximate population-level statistics and broaden our validation exercise, we drew empirical bootstrap samples from each of the datasets described above. 17). In this case, once the number of interviews to reach a new information threshold was determined for each run of a dataset, we divided the number of unique themes identified up to that point by the total number of unique themes. PLOS ONE promises fair, rigorous peer review, Can I use thematic analysis in case study? This method also enables researchers to select different levels of the constituent elements in the processi.e., Base Size, Run Length and New Information Thresholdbased on how confident they wish to be that their interpretations and conclusions are based on a dataset that reached thematic saturation. Qualitative data is defined as non-numerical data, such as text, video, photographs, or audio recordings. Retrieved May 1, 2023, (Under our approach, however, a measure of percent saturation as defined by these authors will not be available.). No, Is the Subject Area "Statistical data" applicable to this article? You can use quantitative analysis to interpret data that was collected either: During an experiment. Can You Do Thematic Analysis In Quantitative Research? What is the similarities between qualitative and quantitative variables? Though there were 14 questions on the guide, only data from three questions were included in the thematic analysis referenced here. Using a meta-analytic approach, Galvin [20] reviewed and statistically analyzedusing binomial logic54 qualitative studies. We describe how often the themes come up and what they mean, including examplesfrom the data as evidence. And lastly, these descriptive statistics help. through semi-structured interviews or open-ended survey questions) and explaining how we conducted the thematic analysis itself. While methods of data collection and data analysis represent the core of research methods, you have to address a range of additional elements within the scope of your research. Data Availability: All relevant data are within the manuscript's Supporting Information files. We would annotate these two extra interviews (indicative of run length) by appending a superscript +2 to the interview number, to indicate a total of eight interviews were completed. Merriam, S. B. That said, a researcher could, with this approach, run and report on saturation analyses of two or more codebooks that contain differing levels of coding granularity. Following this process can also help you avoid confirmation bias when formulating your analysis. https://doi.org/10.1371/journal.pone.0232076.t005. Thematic analysis is an important tool for researchers to consider when conducting quantitative research. Many policy researchers are predisposed to use either quantitative or qualitative research methods regardless of the research questions at hand, leading to varying degrees of gaps in . We additionally propose a more flexible approach to reporting saturation. The method we outline eliminates this problem by using a subset of data items in the denominator instead of the entire dataset, facilitating better prospective assessment of saturation and offering the advantage of allowing researchers to stop before reaching a pre-specified number of interviews. The size of run length effect is smallestvery minimalif employing the 5% new information threshold. From an applied standpoint this finding is important in that researchers can feel confident that choosing a more stringent new information thresholde.g., 0%will result in a more conservative assessment of saturation, if so desired. PLoS ONE 15(5): Thematic analysis is a method that is often used to analyse data in primary qualitative research.
