Quantitative data is any kind of data that can be measured numerically. For example, quantitative data is used to measure things precisely, such as the temperature, the amount of people in a crowd or the height of a structure. Although quantitative data usually involves numbers and equations, some data records actions, such as the frequency of human behavior.Know More
Quantitative research methods are most often used science, psychology and economics. Although quantitative data involves exact measurements, the data is still subject to variables. For example, a researcher gathering quantitative data on the financial earnings of a group of people may not have access to all financial documents, or some earnings may not be reported. However, quantitative data relies less on interpretation, so it is generally considered to be very accurate.
Quantitative data is often analyzed using statistics to record the frequency of occurrences. This kind of data rarely results in a new theory. Instead, most quantitative data builds on existing academic theories.
Quantitative data is often contrasted to qualitative data. Qualitative data is commonly used in the social sciences to record and analyze observations that cannot be measured or quantified, such as the behavior of people. However, qualitative and quantitative data can both be used to investigate the same research question and reach the same conclusion.Learn more about Statistics
Quantitative methods are advantageous because they allow researchers to conduct a broad survey, which involves many subjects and generalization of findings. They also yield accurate results. On the other hand, quantitative methods are rigid and provide less detail on the motivation, attitudes and behavior of study subjects.Full Answer >
Quantitative techniques include methods that focus on objective measurements and analyzing numbers in order to draw conclusions about research subjects. These methods include polls, questionnaires and surveys. They also either describe a phenomenon by measuring it once or perform an experiment in which researchers measure the phenomenon before and after they introduce a treatment.Full Answer >
Statistics as a numerical fact is a piece of numerical information, also known as data, used to describe an event, occurrence or phenomena. Statistics as a discipline uses statistics or numerical pieces of information to solve problems in the everyday world and in academics. Those who work with statistics as a discipline are called statisticians.Full Answer >
The main steps utilized in a statistical investigation include four components: clarifying the problem and formulating questions or hypotheses that can be answered with the data, designing or creating an appropriate experiment that can collect the data required, finding and using the appropriate techniques needed to accurately analyze the collected data, and interpreting the collected data and results so as to answer the questions and hypotheses that were proposed in the first place. The main steps in a statistical investigation are thought to be a cylindrical process that helps ensure that all procedures are completed logically. The aim of opening a statistical investigation is to answer the many questions that are present in the world, and is a technique that has been commonly applied by statisticians.Full Answer >
