Home Consumer Insights Market Research. Quantitative data is defined as the value of data in the form of counts or numbers where each data-set has an unique numerical value associated with it. This data is any quantifiable information that can be used for mathematical calculations and statistical analysis, such that real-life decisions can be made based on these mathematical derivations. This data can be verified and can also be conveniently evaluated using mathematical techniques. There are values associated with most measuring parameters such as pounds or kilograms for weight, dollars for cost etc. Quantitative data makes measuring various parameters controllable due to the ease of mathematical derivations they come with.

Data analysis

Data may be grouped into four main types based on methods for collection: observational, experimental, simulation, and derived. The type of research data you collect may affect the way you manage that data. For example, data that is hard or impossible to replace e. Or, if you will need to combine data points from different sources, you will need to follow best practices to prevent data corruption. Observational data are captured through observation of a behavior or activity. Because observational data are captured in real time, it would be very difficult or impossible to re-create if lost.

Whether you're the world's greatest detective trying to crack a case or a person trying to solve a problem at work, you're going to need information. Data , as Sherlock Holmes says. But not all data is created equal, especially if you plan to analyze as part of a quality improvement project. If you're using Minitab Statistical Software, you can access the Assistant to guide you through your analysis step-by-step , and help identify the type of data you have. But it's still important to have at least a basic understanding of the different types of data, and the kinds of questions you can use them to answer.

Data Module #1: What is Research Data?

Data types are an important aspect of statistical analysis, which needs to be understood to correctly apply statistical methods to your data. There are 2 main types of data, namely; categorical data and numerical data. As an individual who works with categorical data and numerical data, it is important to properly understand the difference and similarities between the two data types. This will make it easy for you to correctly collect, use, and analyze them.

Data Types in Statistics

Students need know that data that they collect can be one of several types. The first distinction is between:. Category - without order Nominal data : This is data with no order between the different categories. Category data - ordered Ordinal data : Thisis when the categories can be put into order. Example: "Very happy" is not twice as happy as "Happy", but it is definitely happier. Often this data involves a subjective judgement, for example, how do you define happy.

Data Types are an important concept of statistics, which needs to be understood, to correctly apply statistical measurements to your data and therefore to correctly conclude certain assumptions about it. This blog post will introduce you to the different data types you need to know, to do proper exploratory data analysis EDA , which is one of the most underestimated parts of a machine learning project. Table of Contents:. Having a good understanding of t h e different data types, also called measurement scales, is a crucial prerequisite for doing Exploratory Data Analysis EDA , since you can use certain statistical measurements only for specific data types.

Studies can use quantitative data, qualititative data, or both types of data. Each approach has advantages and disadvantages. Explore the resources in the box at the left for more information. Hover over the database name below for information on how to do so. Note: database limits are helpful but not perfect. Rely on your own judgment when determining if data match the type you are seeking.

If you're studying for a statistics exam and need to review your data types this article will give you a brief overview with some simple examples. In short: quantitative means you can count it and it's numerical think quantity - something you can count.
