  Quantitative research - Wikipedia, the free encyclopedia
Quantitative research is the systematic scientific investigation of quantitative properties and phenomena and their relationships.
In the social sciences particularly, quantitative research is often contrasted with qualitative research, which is the examination, analysis and interpretation of observations for the purpose of discovering underlying meanings and patterns of relationships, including classifications of types of phenomena and entities, in a manner that does not involve mathematical models.
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.

 Ways of approaching research : Quantitative Designs
Lastly here, the most obvious difference between quantitative research and qualitative research is that quantitative research uses data that are structured in the form of numbers or that can be immediately transported into numbers.
The majority of medical research is quantitative (and considered to produce "hard", generalisable results) whilst much of nursing research is qualitative (and considered to produce "soft" results).
Genuinely quantitative measurement such as that of temperature is measured at the interval level of measurement.

Further, the nature of genetic variation for quantitative traits is expected to differ depending on the relationship of the trait to fitness.
We are using linkage disequilibrium, or association, between nucleotide and insertion/deletion polymorphisms at candidate genes with quantitative phenotypes in random breeding populations to assess the contribution of candidate genes to phenotypic variation, and to identify the causal QTN.
Finally, we are excited about the prospects for linking whole-genome expression studies with variation for quantitative traits, and have begun experiments to determine the extent to which quantitative phenotypic variation is mirrored by quantitative variation in transcription.

 Neuroscience Meets Quantitative Genetics: Using Morphometric Data to Map Genes that Modulate CNS Architecture
Quantitative methods now pervade most aspects of neuroanatomical research, whether the focus is on dendritic spines or the topography of human neocortex.
Quantitative trait loci are normal genes in every sense of the word, but they are referred to using this somewhat unwieldy term to highlight the fact that variant forms—or alleles—of QTLs have relatively subtle quantitative effects on phenotypes (Lynch and Walsh, 1998).
For studies of robust Mendelian and quantitative traits, these sources of variation may not matter much, but if you are trying to track down a host of genes that affect the kinetics of neurogenesis in the hippocampus or of a sensitive behavioral trait then go to the effort to control as much as possible.

 Quantitative - Wikipedia, the free encyclopedia
Measurements of any particular quantitative property are expressed as a specific quantity, referred to as a unit, multiplied by a number.
In classical terms, the structure of a quantitative property is such that different magnitudes of the quantity stand in relation to one another as ratios which, in turn, can be expressed as real numbers.
For example, SI units are physical units of continuous quantitative properties, phenomena, and relations such as distance, mass, heat, force and angular separation.

 Quantitative Analysis
Quantitative analysis can be done for a number of reasons such as measurement, performance evaluation or valuation of a financial instrument.
Although quantitative analysis is a powerful tool for evaluating investments, it rarely tells a complete story without the help of its opposite - qualitative analysis.
In financial circles, quantitative analysts are affectionately referred to as "quants", "quant jockeys" or "rocket scientists".

The ongoing argument over the relative merits of what are generally referred to as qualitative and quantitative research is clouded by two problems: 1) lack of coherent definitions, and 2) the focus of most discussions on methods instead of on the basic assumptions of these two stances.
This paper examines the qualitative "versus" quantitative debate by focussing on the definitions put forward in the library and information science (LIS) literature, identifying the characteristics attributed to the two, and assessing whether or not there is a fundamental difference between them.
The method of this paper is a deconstructive reading which, first, illustrates the arbitrary and fluctuating difference between definitions of qualitative and quantitative research and, second, examines their underlying assumptions.

 Quantitative Literacy: Why Numeracy Matters for Schools and Colleges
Most of the discussion focused on implications for educational policy of a commitment to achieve the appropriate levels of quantitative literacy that Rita Colwell emphasized in her remarks.
He asserted, with uncommon eloquence, that quantitative literacy is not so much about mathematics and democracy as about the "democratization of mathematics." Citing data from many sources, he argued that mathematics education has always been about separation — of rich from poor, of boys from girls, of elites from plebeians.
A second observation, echoed by many participants, is that quantitative literacy is not a curriculum (and certainly not a single course), but an approach to pedagogy.

 Quantitative and Analytical Reasoning Courses
A:  There isn’t a math requirement.  We have a Quantitative and Analytical Reasoning, or “QA” requirement, which may be satisfied by courses from many departments as well as the mathematics department.  See the course schedule for a listing of the QA* and QA courses.
A:  In a nutshell, (QA*) courses are those in which new quantitative methods are learned.  Quantitative methods can include computational methods (including using and deriving formulas) and methods of interpretation of quantitative data (evaluating graphs, tables, formulas, etc.)  (QA) courses require the application of quantitative methods already known.
This is particularly recommended if you think you will go on to major in a field of study which requires quantitative background, or if you wish to take a quantitative course that is closely tied to one you have just completed in high school.

 Peer Review | Summer 2004 | Setting Greater Expectations for Quantitative Learning*
The first change is to identify the ways in which quantitative literacies are actually used in contemporary society.
We should allow college students to develop quantitative strengths keyed to their actual interests, even at the cost of underdeveloping other possible abilities that, realistically, they are unlikely actually to use.
One promising strategy is to make field-related quantitative competence the standard, holding students accountable for evidence of developed ability to actually use quantitative reasoning in ways keyed to their major field(s) of study.

 Quantitative Reasoning: An Overview
Often, quantitative reasoning (QR) is assumed to be synonymous with mathematics, and, indeed, the two are inextricably linked.
While arguably not the most important reason to address QR as a component of a complete education, it is one of four state-mandated student learning outcomes.
The expectation that college graduates will demonstrate competence in quantitative reasoning is broadly supported on both the state and national levels; however, the assessment of QR skills in undergraduates is complicated.

 Organization of Quantitative Data   (Site not responding. Last check: 2007-11-04)
Quantitative data is typically organized by counting instances or events and displaying the results by class, grade level, and school.
The results can be displayed in "charts with numbers and percentages; in simple frequency tables; or in tables showing the mean, median, and range," notes Calhoun (1994, p.
This approach can help identify problems and generate questions that need to be answered in order to create a clear picture of what is occurring within a reading program (Calhoun, 1994).

 Introduction to Quantitative Genetics   (Site not responding. Last check: 2007-11-04)
Because continuous traits are often measured and given a quantitative value, they are often referred to as quantitative traits, and the area of genetics that studies their mode of inheritance is called quantitative genetics.
Many important agricultural traits such as crop yield, weight gain in animals, fat content of meat are quantitative traits, and much of the pioneering research into the modes of inheritance of these traits was performed by agricultural geneticists.
Each trait is controlled by a number of genes and is a quantitative trait.
