These arbitrary divisions create an ordinal categorical variable (ie there is an order or hierarchy). Furthermore
For simplicity of showing data our examples use contingency table data but in general the data ?le may have both categorical and quantitative explanatory variables Example: SAS modeling of mental health y= mental impairment (1=well 2=mild impairment 3=moderate impairment 4=impaired) x1= number of “life events”
B Ordinal variables are variables whose values have a natural order If they are represented as numbers the order of the numerical values should reflect the natural ordering Responses to an item on a questionnaire ranging from “Strongly Disagree” to “Strongly Agree” are ordinal data The letter grades

What are the types of qualitative data?
Types of qualitative data. Researchers and statisticians often categorize qualitative data into three types: 1. Binary data. Binary data is qualitative data that you can characterize by one of two mutually exclusive (meaning they cannot happen simultaneously) traits. For example, something might be good or bad, right or wrong, hard or soft.
What are some examples of quantitative and qualitative data?
Some examples are length, mass, temperature, and time. Quantitative information is often called data. Qualitative Information—Involves a descriptive judgment using concepts (words instead of numbers). What is qualitative and quantitative metrics? Quantitative metrics are those which you can measure in a specific number through certain formulae. It gives you the precise information in mathematical data.
What are qualitative data collection techniques?
