subcategories of measurement scale ordinal and nominal. An ordinal variable is a discrete variable having an order associated with its levels. For example
The GSS also includes some “feeling thermometer” variables and these too are measured at the ordinal level. Examples include FEELBLKS (“In general

Categorical variables take 2 forms-- nominal and ordinal variables. For example – the education level of a household head is recorded.

common view of ordinal variables which is adopted here is that they are nonstrict monotonic transformations of interval vari- ables (e g O'Brien 1981) That is one or more values of an interval-level variable are mapped into the same value of a transformed ordinal variable
The most widely accepted set of rules for determining a variable’s level of measurement is that developed by S Stevens (1946) This typology consists of four levels of measurement whose order is based on how much information they carry These levels are nominal ordinal interval and ratio
or ratio level variables for example a t-test or a hypothesis test of means requires a variable that is at least interval/ratio ) By the way the statistical software program SPSS uses only three categories: nominal ordinal and “scale” where scale includes interval and ratio level variables
qualitative (categorical): nominal and ordinal (ranked) variables (data) quantitative: interval and ratio variables (data) measurements or counts quantitative: discrete versus continuous discrete variable (data): Discrete variable where quantitative data is nite or countable in nite
