Reporting qualitative and quantitative data
The way we typically define them, we call data 'quantitative' if it is in and 'qualitative' if it is ative research is empirical research where the data are not in the form of numbers (punch, 1998, p. This means that qualitative researchers study things in their natural settings, attempting to make sense of, or interpret, phenomena in terms of the meanings people bring to interest in qualitative data came about as the result of the dissatisfaction of some psychologists (e. Aim of qualitative research is to understand the social reality of individuals, groups and cultures as nearly as possible as its participants feel it or live it. Thus, people and groups are studied in their natural ch following a qualitative approach is exploratory and seeks to explain ‘how’ and. Why’ a particular phenomenon, or behavior, operates as it does in a particular s (used to obtain qualitative data). Good example of a qualitative research method would be unstructured interviews which generate qualitative data through the use of open questions.

This helps the researcher develop a real sense of a person’s understanding of a that qualitative data could be much more than or text. The researcher does leave the field with mountains of empirical data and then easily write up her findings. Qualitative interpretations are constructed, and various techniques can be used to make sense of the data, such t analysis, grounded theory (glaser & strauss, 1967), thematic analysis (braun & clarke, 2006) or discourse can be understood adequately only if they are seen in context. Therefore, qualitative research is an interactive process in which the persons studied teach the researcher about their qualitative researcher is an integral part of the data, without the active participation of the researcher, no data design of the study evolves during the research, and can be adjusted or changed as it the qualitative researcher, there is no single reality, it is subjective and exist only in reference to the is data driven, and emerges as part of the research process, evolving from the data as they are e of the time and costs involved, qualitative designs do not generally draw samples from large-scale data problem of adequate validity or reliability is a major criticism. Because of the subjective nature of qualitative data and its origin in single contexts, it is difficult to apply conventional standards of reliability and validity. For example, because of the central role played by the researcher in the generation of data, it is not possible to replicate qualitative studies.
Also, contexts, situations, events, conditions and interactions cannot be replicated to any extent nor can generalisations be made to a wider context than the one studied with any time required for data collection, analysis and interpretation is lengthy. Analysis of qualitative data is difficult and expert knowledge of an area is necessary to try to interpret qualitative data and great care must be taken when doing so, for example, if looking for symptoms of mental e of close researcher involvement, the researcher gains an insider's view of the field. This allows the researcher to find issues that are often missed (such as subtleties and complexities) by the scientific, more positivistic ative descriptions can play the important role of suggesting possible relationships, causes, effects and dynamic ative analysis allows for ambiguities/contradictions in the data, which are a reflection of social reality (denscombe, 2010). Research uses a descriptive, narrative style, this research might be of particular benefit to the practitioner as she or he could turn to qualitative reports in order to examine forms of knowledge that might otherwise be unavailable, thereby gaining new tative tative research gathers data in numerical form which can be put into categories, or in rank order, or measured in units of measurement. This type of data can be used to construct graphs and tables of raw tative researchers aims to establish general laws of behavior and phenonomon across different settings/contexts. Research is used to test a theory and ultimately support or reject s (used to obtain quantitative data).
However, other research methods, such as controlled observations and questionnaires can produce both quantitative example, a rating scale or closed questions on a questionnaire would generate quantitative data as these produce either numerical data or data that can be put into categories (e. Findings are therefore likely to be context-bound and simply a reflection of the assumptions which the researcher brings to the tics help us turn quantitative data into useful information to help with decision can use statistics to summarise our data, describing patterns, connections. Descriptive statistics help us ise our data whereas inferential statistics are used to identify statistically ences between groups of data (such as intervention and control groups in ised control study). Without bias), and is separated from the design of the study is determined before it the quantitative researcher reality is objective and exist separately to the researcher, and is capable of being seen by ch is used to test a theory and ultimately support or reject t: quantitative experiments do not take place in natural settings. Small scale quantitative studies may be less reliable because of low quantity of data (denscombe, 2010). This also affects the ability to generalize study findings to wider mation bias: the researcher might miss observing phenomena because of focus on theory or hypothesis testing rather than on theory of hypothesis ific objectivity: quantitative data can be interpreted with statistical and since statistics are based on the principles of mathematics, the quantitative approach is viewed as scientifically objective, and rational (carr, 1994; denscombe, 2010).
For testing and validating already constructed analysis: sophisticated software removes much of the need for prolonged data analysis, especially with large volumes of data involved (antonius, 2003). Quantitative data is based on measured values and can be checked by others because numerical data is less open to ambiguities of interpretation.

Unported y registration no: ative and quantitative ison of qualitative and quantitative tative and qualitative research are commonly considered to differ fundamentally. Yet, their objectives as well as their applications overlap in numerous tative research is considered to have as its main purpose the quantification of data.
Yet, quantitative research is not infrequently followed by qualitative research which then aims to explore select findings ative research is considered to be particularly suitable for gaining an in-depth understanding of underlying reasons and motivations. At the same time, it frequently generates ideas and hypotheses for later quantitative main differences between quantitative and qualitative research consist in respect to data sample, data collection, data analysis, and last but not least in regard to collection in qualitative research is not seldom based on unstructured or semi-structured, but methodologically flexible techniques, e. Quantitative research uses highly structured, rigid techniques such as online questionnaires, on-street or telephone interviews. Unlike qualitative research, which allows unlimited expression from respondents, quantitative research relies responses to pre-formulated es: qualitative research typically is exploratory and/or investigative in nature. Quantitative research is essential for providing a broad base of insight on which typically a final course of action is selection in qualitative research is usually based on a smaller number of not-necessarily representative cases. In quantitative research, sample selection seeks out a large number of cases that are expected to best represent the population of interest.
Individual respondents are selected at ative data analysis is non-statistical, its methodological approach is primarily guided by the concrete material at hand. In quantitative research, the sole approach to data is statistical and takes places in the form of tabulations. Findings are usually descriptive in nature although conclusive only within the numerical is a frequently held prejudice that quantitative research is “objective” vs. Rather, one could compare the two approaches as follows: quantitative research seeks out explanatory laws whereas qualitative research aims more at in-depth description. Qualitative research measures, in hopes of developing universal laws where qualitative research can be described as an exploration of what is assumed to be a dynamic reality. Qualitative research does not claim that what is discovered in the process is universal, and thus, replicable.
Common differences usually cited between these types of research general, qualitative research generates rich, detailed and valid process data that contribute to the in-depth understanding of a context. Quantitative research, on the other hand, generates reliable population-based and generalizable data that is suited to establishing cause-and-effect relationships. The decision of whether to choose a quantitative or a qualitative design is ultimately a philosophical question.

When presenting data in all three forms, care should be taken to include only information and/or images that help to clarify points being reference purposes, tables are usually the sensible option. When presented, care should be taken to do so in a way that does not obscure the main message of the table or ting data in charts and and graphs are often the best way to demonstrate trends in data and make comparisons between different groups. Charts emphasize general findings, but do not make small differences charts should only be used to represent categorical data with a relatively small number of values and should not consist of more than five or six presenting a pie chart, it is better not to use 3-d features, or break out the pieces, as this often makes it more difficult to compare the relative size of the is always necessary to include category labels or a legend that describes which slice corresponds with which category. Is also good to pre-sort data so that, clockwise or counter-clockwise, the relative size of pie slices is most purpose of color in pie charts is to differentiate between pie slices to further facilitate comparison. Bar graph, rather than multiple pie graphs, is the better option if data need to be compared by more than one value. Pie graphs should not be used to represent more than one categorization of graphs are used for direct comparison of data (e.

Graphs can also be used to show time series data when the number of time intervals is all values are positive integers, the scale should generally use 0 as a baseline. The complexity of 3-d graphs makes them ineffective in conveying results to most audiences and there is usually a greater amount of data distortion that graphs may be vertical or horizontal. The most common and visually effective schema is according to size of may also be desirable to order findings by a particular category such as class year (see clustered bar graph below), where it is best to order sequentially from freshman to senior year or visa versa, or by grade achieved, where it is best to order by the standardized grade d bar graphs, which consist of one or more segmented bars where each segment represents the relative share of a total category, are generally not preferred because it is difficult to make comparisons among the second, third, or subsequent segments without a standard graphing data from two or more different series, or different classes within the same series, it is preferable to create a bar graph that groups these values together, side by side (see below). See graph ed with bar graphs, line graphs are more effective in presenting five or more data points, but less effective in providing emphasis on differences over relatively few periods of plotting time series data in a line graph, it is convention that the x-axis (horizontal) contains the categories of time (e. Days of the week, months, years – depending on the data), and the y-axis (vertical) has frequencies of what is being measured (see graphs below).
