Social science

social sciencessocial sciencesocial scientist
In natural sciences and social sciences, quantitative research is the systematic empirical investigation of observable phenomena via statistical, mathematical, or computational techniques.
In modern academic practice, researchers are often eclectic, using multiple methodologies (for instance, by combining both quantitative and qualitative research).

Measurement

measurementmeasuremeasuring
The process of measurement is central to quantitative research because it provides the fundamental connection between empirical observation and mathematical expression of quantitative relationships.
Measurement is a cornerstone of trade, science, technology, and quantitative research in many disciplines.

Observation

observationobserverobservations
The process of measurement is central to quantitative research because it provides the fundamental connection between empirical observation and mathematical expression of quantitative relationships.
Observations can be qualitative, that is, only the absence or presence of a property is noted, or quantitative if a numerical value is attached to the observed phenomenon by counting or measuring.

Empirical research

empirical researchempiricalempirical evidence
In natural sciences and social sciences, quantitative research is the systematic empirical investigation of observable phenomena via statistical, mathematical, or computational techniques.
Empirical evidence (the record of one's direct observations or experiences) can be analyzed quantitatively or qualitatively. Quantifying the evidence or making sense of it in qualitative form, a researcher can answer empirical questions, which should be clearly defined and answerable with the evidence collected (usually called data).

Sociology

In social sciences, quantitative research is widely used in psychology, economics, demography, sociology, marketing, community health, health & human development, gender and political science, and less frequently in anthropology and history.
Social researchers draw upon a variety of qualitative and quantitative techniques.

Qualitative research

qualitative researchqualitativequalitative methods
Qualitative research, on the other hand, inquires deeply into specific experiences, with the intention of describing and exploring meaning through text, narrative, or visual-based data, by developing themes exclusive to that set of participants. In the social sciences, the term relates to empirical methods, originating in both philosophical positivism and the history of statistics, which contrast with qualitative research methods.
Quantitative methods can be then used to seek further mathematical support for such research hypotheses.

Positivism

In the social sciences, the term relates to empirical methods, originating in both philosophical positivism and the history of statistics, which contrast with qualitative research methods.
Positivism in the social sciences is usually characterized by quantitative approaches and the proposition of quasi-absolute laws.

Descriptive statistics

descriptive statisticsdescriptive statisticdescriptive
Quantitative data is any data that is in numerical form such as statistics, percentages, etc. The researcher analyses the data with the help of statistics and hopes the numbers will yield an unbiased result that can be generalized to some larger population.
Such summaries may be either quantitative, i.e. summary statistics, or visual, i.e. simple-to-understand graphs.

Market research

There are two major types of market research: primary research, which is sub-divided into quantitative and Qualitative research, and secondary research.

Marketing

In social sciences, quantitative research is widely used in psychology, economics, demography, sociology, marketing, community health, health & human development, gender and political science, and less frequently in anthropology and history.
Marketing researchers use statistical methods (such as quantitative research, qualitative research, hypothesis tests, Chi-square tests, linear regression, correlation coefficients, frequency distributions, Poisson and binomial distributions, etc.) to interpret their findings and convert data into information.

Survey methodology

Polls about public opinion, public-health surveys, market-research surveys, government surveys and censuses are all examples of quantitative research that use survey methodology to answer questions about a population.

Scientific method

Quantitative research is generally closely affiliated with ideas from 'the scientific method', which can include:

Acid dissociation constant

pKap''K'' a acid dissociation constant
An acid dissociation constant, K a, (also known as acidity constant, or acid-ionization constant) is a quantitative measure of the strength of an acid in solution.

Titration

Titration, also known as titrimetry, is a common laboratory method of quantitative chemical analysis that is used to determine the concentration of an identified analyte.

Risk assessment

risk assessmentrisk assessmentsassessment
Put in simpler terms, a risk assessment analyzes what can go wrong, how likely it is to happen, what the potential consequences are, and how tolerable the identified risk is. As part of this process, the resulting determination of risk may be expressed in a quantitative or qualitative fashion.

Marketing research

It is the systematic gathering, recording, and analysis of qualitative and quantitative data about issues relating to marketing products and services.

Climate model

Climate models use quantitative methods to simulate the interactions of the important drivers of climate, including atmosphere, oceans, land surface and ice.

Human geography

As an intellectual discipline, geography is divided into the sub-fields of physical geography and human geography, the latter concentrating upon the study of human activities, by the application of qualitative and quantitative research methods.
