Suppose you're given a data set that classifies each sample unit into one of four categories: A, B, C, or D. You plan to create a computer database consisting of these data, and you decide to code the data as A Equals1, B Equals2, Equals3, and Dequals4. Are the data consisting of the classifications A, B, C, and D qualitative or quantitative?
The data is qualitative because they can only be classified into the four categories and they cannot be measured on a numerical scale. Therefore, we know the data is qualitative.
