Abstract
There are three types of statistical data. The three types of statistical data are numerical, categorical, and ordinal. Numerical data is used for measurement, for example, the height of a person and miles to New York City. You can make mathematical operations on numerical data and the resulting number has meaning. Categorical data represents characteristics, for example, male or female and true or false. Ordinal data has ranking. For example, an experience could be poor, fair, and excellent. In this chapter we will do statistical tests on ordinal data.
