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.Continue Reading
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
Qualitative data is data that is not numerical, such as colors, smells or tastes. Quantitative data is measurable with numbers, like height and weight. Objects can have both quantitative and qualitative data.Full Answer >
Statistics allow people to analyze surveys, experiments and other data, but they are easy to misrepresent or to use to mislead others. Statistical data is essential to the scientific method. It also helps companies, governments and other entities make decisions.Full Answer >
Discrete data refers to data that has values that are different and separable from one another. This form of data typically represents items that can be counted. Some examples of discrete data include eye color and the number of pushups that someone can perform. This form of data is one of three main data types, along with continuous and categorical data.Full Answer >
Modal value refers to the mode in mathematics, which is the most common number in a set of data. For example, in the data set 1, 2, 2, 3, the modal value is 2, because it is the most common number in the set.Full Answer >
