Turning qualitative into quantitative evidence: a well-used method made Many historians reject quantitative methods as inappropriate to understanding past societies. The nominal data can then be quantitatively analysed with charts and graphs, measures of central tendency and dispersion produced and statistical analysis can be carried out. When dealing with written/qualitative data it is not possible to use descriptive or inferential statistics. Qualitative research differs from quantitative research in many diverse ways, for instance, quantitative research methodologies are specialised, standard sets of data analysis techniques that do not begin analysis on the data until it has been collected and condensed into numerical form. I experienced this problem during a recent project. A report is then written up whereby the researcher will need to present a case for each theme and provide some supporting quotations from the text. Table of Contents; Foundations; Language Of Research; Types of Data; Types of Data. Again, this is necessary to prevent “double counting.”. This format also makes it easy to compare and contrast responses against each other. Sorry, your blog cannot share posts by email. So far very helpful! It gives access to human experience and allows researchers to describe intimate aspects of people's life worlds. Content Analysis. Content analysis is a method of qualitative data analysis that involves rating or coding and categorising qualitative data. quantitative data is any information that can be reduced to a set of numbers. In the scientific community, and particularly in psychology and health, there has been an active and ongoing debate on the relative merits of adopting either quantitative or qualitative methods, especially when researching into human behaviour (Bowling, 2009; Oakley, 2000; Smith, 1995a, 1995b; Smith, 1998). Some companies find it difficult to digest large data sets derived from survey text questions or interview comments and quotes collected over a long period of time. Although quantitative and qualitative research generally differ along several important dimensions (e.g., the specificity of the research question, the type of data collected), it is the method of data analysis that distinguishes them more clearly than anything else. If you paste a lot of data into this sheet and the last row of data is below C18, right click on the C18 in the formula (to change that element), and then click on the cell in column “C” of the last row with data. (+) A strength of using a content analysis is that Statistical procedures become possible. In this step we will summarize the data. In this study, data will be analysed using both the qualitative and quantitative method. Contact GP Strategies today to get started. The strength of quantitative data is that it is objective. Everything is either 1 or 0“ - Fred Kerlinger Miles & Huberman (1994). It is important that the major category is only counted once for each relevant verbatim (row) (Figure 6). Because I used numbers in the major categories (rather than an “x” as I did in the sub-categories), I changed my Excel formula slightly. From qualitative hypotheses to quantitative data modeling. I consider the story I want to tell from the data, the audience visualization needs, and the decision this data informs. One way of converting qualitative data into quantitative data is through a content analysis. Although this data can appear very detailed and complicated, one way of simplifying this data to make it easier to analyse and interpret is by converting it into quantitative data. Quantitative has a lot to do with the quantity of an object or a person. Below, I break down how to quantify qualitative data. Figure 2 To learn more about how to incorporate cost-efficient usability testing into your designs, check out the free e-book User Testing & Design. A similar process can be followed where there is no pre-existing theory and, instead, the themes or categories emerge from the data (from the bottom-up). Quantitative Article The quantitative study I chose to critique is, “Effectiveness of turning with unequal time intervals on the incidence of pressure ulcer lesions” (Vanderwee, Grypdonck, De Bacquer, & Defloor, 2010). The two main data types in business are nominal (categorical or qualitative data) and interval data (quantitative or continuous data). These qualitative answers can be very powerful because they have a direct line of sight to the target audience’s thoughts, feelings, and emotions. If you think you may present to your leadership team, they may not be interested in this level of detail. Qualitative data is descriptive, which is more difficult to analyze then quantitative data which is categorized, ranked, or in units of measurement. quality rather than quantity). (1) Transcribe the data if you need to, number each line and read the text through several times until you know it well. Doing Qualitative Research in Psychology.
