what are the different types of models in quantitative methods and how they are used in QM?

Answer 1

Quantitative methods are research methods dealing with numbers and anything that is measurable. They are therefore to be distinguished from qualitative methods.

Counting and measuring are common forms of quantitative methods. The result of the research is a number, or a series of numbers. These are often presented in tables, graphs or other forms of statistics.

In most physical and biological sciences, the use of either quantitative or qualitative methods is uncontroversial, and each is used when appropriate. In the social sciences, particularly in sociology, social anthropology and psychology, the use of one or other type of method has become a matter of controversy and even ideology, with particular schools of thought within each discipline favouring one type of method and pouring scorn on to the other. Advocates of quantitative methods argue that only by using such methods can the social sciences become truly scientific; advocates of qualitative methods argue that quantitative methods tend to obscure the reality of the social phenomena under study because they underestimate or neglect the non-measurable factors, which may be the most important.

The modern tendency (and in reality the majority tendency throughout the history of social science) is to use eclectic approaches. Quantitative methods might be used with a global qualitative frame. Qualitative methods might be used to understand the meaning of the numbers produced by quantitative methods. Using quantitative methods, it is possible to give precise and testable expression to qualitative ideas.

Examples of Quantitative research
Research that consists of the percentage amounts of all the elements that make up our atmosphere
Protest/Survey which concludes that the average patient has to wait 2 hours in the waiting room of a certain doctor before being selected.
An experiment in which group x was given two tablets of Aspirin a day and Group y was given two tablets of Tylenol a day where each participant is randomly assigned to one or other of the groups.
The numerical factors such as two tablets, percent of elements and the time of waiting makes the situations and results quantitatives
