Quantitative data is information about quantities; that is, information that can be measured and written down with numbers. Some examples of quantitative data are your height, your shoe size, and the length of your fingernails. You've got to be close to breaking the ative data is information about qualities; information that can't actually be measured. Some examples of qualitative data are the softness of your skin, the grace with which you run, and the color of your eyes. However, try telling photoshop you can't measure color with 's a quick look at the difference between 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.
Qualitative data and quantitative data
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.

Primary data is the data acquired by the researcher to address the problem at hand, which is classified as qualitative data and quantitative data. Qualitative data is a data concerned with descriptions, which can be observed but cannot be the contrary, quantitative data is the one that focuses on numbers and mathematical calculations and can be calculated and data types are used in a number of fields like marketing, sociology, business, public health and so on.

Hence, the researcher should possess complete knowledge about the type of characteristic, prior to the collection of nature of data is descriptive and so it is a bit difficult to analyze it. This type of data can be classified into categories, on the basis of physical attributes and properties of the object. It is concerned with the data that is observable in terms of smell, appearance, taste, feel, texture, gender, nationality and so on. The methods of collecting qualitative data are:Archival materials like tion of quantitative tative data, as the name suggests is one which deals with quantity or numbers. It refers to the data which computes the values and counts and can be expressed in numerical terms is called quantitative data. In statistics, most of the analysis are conducted using this tative data may be used in computation and statistical test.
The tabular and diagrammatic presentation of data is also possible, in the form of charts, graphs, tables, etc. The methods used for the collection of data are:Observations and differences between qualitative and quantitative fundamental points of difference between qualitative and quantitative data are discussed below:The data type, in which the classification of objects is based on attributes (quality) is called qualitative data. The type of data which can be counted and expressed in numbers and values is called quantitative research methodology is exploratory in qualitative data, i. On the other hand, quantitative data is conclusive in nature which aims at testing a specific hypothesis and examine the approach to inquiry in the case of qualitative data is subjective and holistic whereas quantitative data has an objective and focused the data type is qualitative the analysis is non-statistical. As opposed to quantitative data which uses statistical qualitative data, there is an unstructured gathering of data. As against this, data collection is structured in quantitative qualitative data determines the depth of understanding, quantitative data ascertains the level of tative data is all about ‘how much or how many’. Qualitative data the sample size is small and that too is drawn from non-representative samples. Conversely, the sample size is large in quantitative data drawn from the representative ative data develops initial understanding, i.
Unlike quantitative data, which recommends the final course of , for the collection and measurement of data, any of the two methods discussed above can be used. Both are used in conjunction so that the data gathered is free from any errors. Further, both can be acquired from the same data unit only their variables of interest are different, i.

Type of data you collect depends on the question you want to answer and your resources. As discussed in module four (click here to review this module), there are two types of data: qualitative and quantitative. Both types of data have strengths and limitations and may be appropriate for different settings, evaluation designs, and evaluation ative data consist of words and narratives.
The analysis of qualitative data can come in many forms including highlighting key words, extracting themes, and elaborating on concepts. The type of data you collect guides the analysis example of qualitative data would be if you conducted a focus group with parents participating in an education program to understand participant perceptions. In this case the data that you collected was probably narrative in form, so you would use qualitative techniques to analyze the transcripts looking for content and themes relevant to the example of quantitative data would be if you administered a satisfaction survey asking participants to rate their experience on a scale of 1 to 5. In this case the data would be numeric in form and you would use statistical techniques to draw conclusions about participant two tables below detail the strengths and limitations of both types of give a nuanced understanding of the perspectives and needs of program help support or explain results indicated in quantitative of detailed or “rich” information which can be used to identify patterns of lend itself to working with smaller populations, which may not be representative of larger analysis can be time is can be subjective; there is potential for evaluator bias in analysis/te and reliable if properly be easily communicated via charts and large datasets already exist that can be collection methods provide respondents with a limited number of response require complex sampling not accurately describe a complex es some expertise with statistical is data analysis?
