By Dr. Saul McLeod , updated Jump to Quantitative Research Data. Qualitative research is the process of collecting, analyzing, and interpreting non-numerical data, such as language. Qualitative research can be used to understand how an individual subjectively perceives and gives meaning to their social reality. Qualitative data is defined as non-numerical data, such as text, video, photographs or audio recordings.

This type of data can be collected using diary accounts or in-depth interviews, and analyzed using grounded theory or thematic analysis. Qualitative research is multimethod in focus, involving an interpretive, naturalistic approach to its subject matter. 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 them. An interest in qualitative data came about as the result of the dissatisfaction of some psychologists e.

Since psychologists study people, the traditional approach to science is not seen as an appropriate way of carrying out research, since it fails to capture the totality of human experience and the essence of what it is to be human. Exploring the experience of participants is known as a phenomenological approach re: Humanism. The 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 setting. It can be used to generate hypotheses and theory from the data. The results of qualitative methods provide a deep understandings of how people perceive their social realities, and in consequence, how they act within the social world. The researcher has several methods for collecting empirical materials, ranging from the interview to direct observation, to the analysis of artifacts, documents, and cultural records, to the use of visual materials or personal experience.

A good example of a qualitative research method would be unstructured interviews which generate qualitative data through the use of open questions. This allows the respondent to talk in some depth, choosing their own words.

Notice that qualitative data could be much more than just words or text. Photographs, videos, sound recordings and so on, can be considered qualitative data.

Qualitative research is endlessly creative and interpretive. The researcher does not just leave the field with mountains of empirical data and then easily write up his or her findings. Because of the time and costs involved, qualitative designs do not generally draw samples from large-scale data sets. The 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 generalizations be made to a wider context than the one studied with any confidence.

The time required for data collection, analysis and interpretation are 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 illness. Because 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 inquiries. Qualitative descriptions can play the important role of suggesting possible relationships, causes, effects and dynamic processes.

Qualitative 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 insight. Quantitative research involves the process of objectively collecting and analyzing numerical data to describe, predict, or control variables of interest. Research is used to test a theory and ultimately support or reject it.

Experiments typically yield quantitative data, as they are concerned with measuring things. However, other research methods, such as controlled observations and questionnaires can produce both quantitative information. For 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.

Experimental methods limit the possible ways in which a research participant can react to and express appropriate social behavior. Findings are therefore likely to be context-bound and simply a reflection of the assumptions which the researcher brings to the investigation. Statistics help us turn quantitative data into useful information to help with decision making. We can use statistics to summarise our data, describing patterns, relationships, and connections.

Statistics can be descriptive or inferential. Descriptive statistics help us to summarise our data whereas inferential statistics are used to identify statistically significant differences between groups of data such as intervention and control groups in a randomised control study.

Context: Quantitative experiments do not take place in natural settings. In addition, they do not allow participants to explain their choices or the meaning of the questions may have for those participants Carr, Researcher expertise: Poor knowledge of the application of statistical analysis may negatively affect analysis and subsequent interpretation Black, Variability of data quantity: Large sample sizes are needed for more accurate analysis.

Small scale quantitative studies may be less reliable because of the low quantity of data Denscombe, This also affects the ability to generalize study findings to wider populations.

Confirmation bias: The researcher might miss observing phenomena because of focus on theory or hypothesis testing rather than on the theory of hypothesis generation. Scientific objectivity: Quantitative data can be interpreted with statistical analysis, and since statistics are based on the principles of mathematics, the quantitative approach is viewed as scientifically objective, and rational Carr, ; Denscombe, Rapid analysis: Sophisticated software removes much of the need for prolonged data analysis, especially with large volumes of data involved Antonius, Replication: Quantitative data is based on measured values and can be checked by others because numerical data is less open to ambiguities of interpretation.

Toggle navigation. Research Methods Qualitative vs. Qualitative Research Quantitative Research. There are different types of qualitative research methods including diary accounts, in-depth interviews , documents, focus groups , case study research , and ethnography. Events can be understood adequately only if they are seen in context. The contexts of inquiry are not contrived; they are natural. Nothing is predefined or taken for granted. Qualitative researchers want those who are studied to speak for themselves, to provide their perspectives in words and other actions.

Therefore, qualitative research is an interactive process in which the persons studied teach the researcher about their lives. The qualitative researcher is an integral part of the data, without the active participation of the researcher, no data exists. The design of the study evolves during the research, and can be adjusted or changed as it progresses. For the qualitative researcher, there is no single reality, it is subjective and exist only in reference to the observer.

Theory is data driven, and emerges as part of the research process, evolving from the data as they are collected. The goals of quantitative research are to test causal relationships between variables , make predictions, and generalize results to wider populations. Quantitative researchers try to control extraneous variables by conducting their studies in the lab.

The research aims for objectivity i. The design of the study is determined before it begins. For the quantitative researcher reality is objective and exist separately to the researcher, and is capable of being seen by anyone.

Social research methods : qualitative and quantitative approaches

Ben-Eliyahu completed her doctorate in developmental psychology at Duke University, where she honed very strong skills in methods. Prior to arriving at Boston, Dr. In the world of research, there are two general approaches to gathering and reporting information: qualitative and quantitative approaches. The qualitative approach to research is focused on understanding a phenomenon from a closer perspective. The quantitative approach tends to approximate phenomena from a larger number of individuals using survey methods. In this research corner, I describe methods that are generally used in each strand of research.

Quantitative methods emphasize objective measurements and the statistical, mathematical, or numerical analysis of data collected through polls, questionnaires, and surveys, or by manipulating pre-existing statistical data using computational techniques. Quantitative research focuses on gathering numerical data and generalizing it across groups of people or to explain a particular phenomenon. Babbie, Earl R. The Practice of Social Research. Your goal in conducting quantitative research study is to determine the relationship between one thing [an independent variable] and another [a dependent or outcome variable] within a population. Quantitative research designs are either descriptive [subjects usually measured once] or experimental [subjects measured before and after a treatment].

Researchers often have issues choosing which research method to go with: quantitative or qualitative research methods? Many incorrectly think the two terms can be used interchangeably. Qualitative research is regarded as exploratory and is used to uncover trends in thoughts and opinions, while quantitative research is used to quantify the problem by way of generating numerical data or data that can be transformed into usable statistics. At the end of this article, you will understand why you should consider using quantitative research instead of qualitative method in your research surveys.

Qualitative Research Qualitative research is somewhat subjective. Uses a problem or open-ended, free response format to investigate the value of programs or probe other questions usually informal. Qualitative and quantitative research have several advantages and disadvantages, depending upon the researcher's aim and area of focus. Qualitative research is useful during the early stages of a study when the researcher may be unsure of exactly what will be studied or what to focus on.
