How Quantitative Research Works

A comprehensive analysis of articles published in the top two American sociology journals between and found that roughly two thirds of these articles used quantitative method.

Quantitative research is generally closely affiliated with ideas from 'the scientific method' , which can include:. Quantitative research is often contrasted with qualitative research , which purports to be focused more on discovering underlying meanings and patterns of relationships, including classifications of types of phenomena and entities, in a manner that does not involve mathematical models.

Although a distinction is commonly drawn between qualitative and quantitative aspects of scientific investigation, it has been argued that the two go hand in hand. Although quantitative investigation of the world has existed since people first began to record events or objects that had been counted, the modern idea of quantitative processes have their roots in Auguste Comte 's positivist framework. Positivist scholars like Comte believed only scientific methods rather than previous spiritual explanations for human behavior could advance.

Quantitative methods are an integral component of the five angles of analysis fostered by the data percolation methodology, [7] which also includes qualitative methods, reviews of the literature including scholarly , interviews with experts and computer simulation, and which forms an extension of data triangulation. Quantitative methods have limitations.

These studies do not provide reasoning behind participants' responses, they often do not reach underrepresented populations, and they may span long periods in order to collect the data. Statistics is the most widely used branch of mathematics in quantitative research outside of the physical sciences, and also finds applications within the physical sciences, such as in statistical mechanics. Statistical methods are used extensively within fields such as economics, social sciences and biology.

Quantitative research using statistical methods starts with the collection of data, based on the hypothesis or theory. Usually a big sample of data is collected — this would require verification, validation and recording before the analysis can take place.

Causal relationships are studied by manipulating factors thought to influence the phenomena of interest while controlling other variables relevant to the experimental outcomes. In the field of health, for example, researchers might measure and study the relationship between dietary intake and measurable physiological effects such as weight loss, controlling for other key variables such as exercise.

Quantitatively based opinion surveys are widely used in the media, with statistics such as the proportion of respondents in favor of a position commonly reported. In opinion surveys, respondents are asked a set of structured questions and their responses are tabulated.

In the field of climate science, researchers compile and compare statistics such as temperature or atmospheric concentrations of carbon dioxide. Empirical relationships and associations are also frequently studied by using some form of general linear model , non-linear model, or by using factor analysis. A fundamental principle in quantitative research is that correlation does not imply causation , although some such as Clive Granger suggest that a series of correlations can imply a degree of causality.

This principle follows from the fact that it is always possible a spurious relationship exists for variables between which covariance is found in some degree. Associations may be examined between any combination of continuous and categorical variables using methods of statistics. Views regarding the role of measurement in quantitative research are somewhat divergent.

Measurement is often regarded as being only a means by which observations are expressed numerically in order to investigate causal relations or associations. However, it has been argued that measurement often plays a more important role in quantitative research.

Thanks for all the great advice. As a professional researcher, I can say if you use both, you will see the benefits. What are quantitative techniques and qualitative techniques? When using both methods of research, is that known as a 'Hybrid Study'? From the researcher of the quantitative and qualitative standpoint to see the blueprint, what are the mathematical formulas they use in this analysis to get the results?

Both qualitative and quantitative research are equally important in their respective field and no one can stand itself without the help of each other. Qualitative 1 is based to make hypothesis like woman like chocolate more than men. Quantitative and qualitative still confuse me.

It seems like both quantitative and qualitative research are important for social scientists. I would imagine that it is very difficult to be totally objective when conducting research, both quantitative and qualitative, but more so qualitative.

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. Qualitative researchers use a variety of methods to develop deep understandings of how people perceive their social realities and in consequence, how they act within the social world.

For example, diary accounts, open-ended questionnaires , documents, participant observation , and ethnography. 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 gathers data in a 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 data. 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.

Jun 09,  · Quantitative research is a type of empirical investigation. That means the research focuses on verifiable observation as opposed to theory or logic. Most often this type of research is expressed in numbers. A researcher will represent and manipulate certain observations that they are studying. They Author: April Klazema.

Introduction to quantitative research What is quantitative research? Research methods in education (and the other social sciences) are often divided into two main types: quantitative and qualitative methods. This book will discuss one of these two main strands: ‘quantitative methods’. 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.
