Quantitative research methodology definition

Quantitative research is generally closely affiliated with ideas from 'the scientific method'which can include: The generation of models, theories and hypotheses The development of instruments and methods for measurement Experimental control and manipulation of variables Collection of empirical data Modeling and analysis of data Quantitative research is often contrasted with qualitative researchwhich 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.

Quantitative research methodology definition

Bibliography Definition 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. The Practice of Social Research. Wadsworth Cengage, ; Muijs, Daniel. Characteristics of Quantitative 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].

A descriptive study establishes only associations between variables; an experimental study establishes causality. Quantitative research deals in numbers, logic, and an objective stance. Quantitative research focuses on numeric and unchanging data and detailed, convergent reasoning rather than divergent reasoning [i.

Its main characteristics are: The data is usually gathered using structured research instruments. The results are based on larger sample sizes that are representative of the population.

Characteristics of Quantitative Research

The research study can usually be replicated or repeated, given its high reliability. Researcher has a clearly defined research question to which objective answers are sought. All aspects of the study are carefully designed before data is collected.

Data are in the form of numbers and statistics, often arranged in tables, charts, figures, or other non-textual forms.

Definition

Project can be used to generalize concepts more widely, predict future results, or investigate causal relationships. Researcher uses tools, such as questionnaires or computer software, to collect numerical data. The overarching aim of a quantitative research study is to classify features, count them, and construct statistical models in an attempt to explain what is observed.

Things to keep in mind when reporting the results of a study using quantitative methods: Explain the data collected and their statistical treatment as well as all relevant results in relation to the research problem you are investigating.

Interpretation of results is not appropriate in this section. Report unanticipated events that occurred during your data collection.

Explain how the actual analysis differs from the planned analysis. Explain your handling of missing data and why any missing data does not undermine the validity of your analysis.

Explain the techniques you used to "clean" your data set. Choose a minimally sufficient statistical procedure; provide a rationale for its use and a reference for it.

Specify any computer programs used. Describe the assumptions for each procedure and the steps you took to ensure that they were not violated. When using inferential statistics, provide the descriptive statistics, confidence intervals, and sample sizes for each variable as well as the value of the test statistic, its direction, the degrees of freedom, and the significance level [report the actual p value].

Avoid inferring causality, particularly in nonrandomized designs or without further experimentation. Use tables to provide exact values; use figures to convey global effects.

Keep figures small in size; include graphic representations of confidence intervals whenever possible.

Always tell the reader what to look for in tables and figures. When using pre-existing statistical data gathered and made available by anyone other than yourself [e. Wadsworth Cengage, ; Brians, Craig Leonard et al.

Quantitative research is the numerical representation and manipulation of observations for the purpose of describing and explaining the phenomena that those observations reflect. Research Methods; Qualitative vs. Quantitative ; Qualitative vs.

Quantitative Research. By Saul McLeod, updated There exists a fundamental distinction between two types of data: qualitative and quantitative.

The way we typically define them, we call data 'quantitative' if it is in numerical form and 'qualitative' if it is not. What is quantitative research?
