What do the term quantitative methods refer to and how can quantitative methods (QM) help me in my field? This term refers to the mathematical approaches that may be used to accurately describe events and to measure or estimate them. They are often used in the fields of science and research to determine how often an event occurs. These data will then be displayed graphically, which is another example of QM. In short, they refer to the total manipulation of information.

Quantitative methods deal with the accumulation, interpretation, and proper display of all forms of data. QM has to do with everything related to the application of mathematical analyses to a specified set of data or individual phenomenon, whether they be the migration penguins, as seen in the fields of natural science or the measurement of a stock's performance in the investment world. Both of these types of data will be subjected to that kind of methods to determine the actual occurrence of events, their relative change over time and the properties they display, such as consistency or changeability.

## Other Uses

They can also be applied to all fields of science and to business uses such as inventory and marketing techniques. QM are used in areas such as crowd control wherein a sample set of the number of people attending an event is evaluated to determine if there are adequate facilities to service the population and to transport them. Modern day concerts would not run smoothly without them. Indeed, event organizers could not live without them.

Psychology is another field that uses quantitative methods to organize data from studies and portray it graphically. Also, they are especially important in medical research where events such as the response to a drug must be tabulated and evaluated. They are very important in determining the safety of many products that are released upon the market. No matter what field you are in or business you are a part of, you probably use quantitative methods to organize and illustrate the various aspects. They will prove to be essential in the sales and marketing fields to determine the amount of product on hand, the amount sold and the amount needed to keep up with demand. All of these figures will be determined using such techniques.

## QM and Statistics

The study of QM heavily includes the use of statistical analyses and definitely, the field of Quantitative methods is largely based upon the compilation of statistics. Once the data are assembled and collected, they are subjected to scrutiny, in order to evaluate each parameter. After the basic quantitative assessment is finished, diverse theoretical methods can be applied that will predict the change over time. This is often used to predict how a stock will perform in the stock exchange, or an investment will grow over time.

QM can be used as a predictive tool and it can be used as well in this way by assessing the past performance and identifying the factors that affected this performance. Then QM methods are applied with each of the variables eliminated to determine how to enhance performance.
