Sometimes, nominal data can result in only two characteristics, such as equal and unequal. As such, you can use nominal measurement to categorize data without a ranking order. Nominal data often contains the least amount of information content because it's the lowest level of measurement. The analyst can categorize the data into categories like: For instance, consider a marketing analyst who collects information from consumers. While this level of measurement is incompatible with ordering and data calculations, it can help provide basic information about distinctions between your data. Nominal measurement organizes data by labeling items in mutually exclusive categories. Here are the four levels of measurement that you can use to organize your data and perform a statistical analysis: 1. Reliability: What's the Difference? 4 levels of measurement Levels of measurement apply to variables ranging from test scores and height to temperature. The most basic level of measurement indicates one can exclusively categorize a variable, while more complex levels of measurement indicate that the variable is compatible with descriptors like ranking, the inference of equal intervals and the presence of true zero points. Levels of measurement, or scales of measurement, are descriptors that indicate the precision with which you can record variables. In this article, we explain what levels of measurement are, discuss the four key types and explore why they're important in data analysis. Learning about the four levels of measurement allows statisticians and analysts to more efficiently plan for research and present their findings. You can describe the varying degree of complexity using levels of measurement, which help you categorize data by how you can analyze it. When gathering data for analysis, you might notice that the information varies in degree of complexity from past analyses.
