Exercise 33 Page 758

What is the difference between quantitative and qualitative data? How many variables are involved?

Qualitative and bivariate

Practice makes perfect
Before classifying the data as qualitative or quantitative and as univariate or bivariate, let's recall the definitions of these classifications.
Types of Data Description
Can It Be Measured? Quantitative Has units and can be measured and numerically compared.
Qualitative Describes a category and cannot be measured or numerically compared.
Number of Variables Univariate A set of data that uses only one variable.
Bivariate A set of data that uses two variables.

Let's now consider our data set.

Names of U.S. presidents and the states they were born in

Names are not a numerical quantity. They cannot be measured and numerically compared to other names. Therefore, the data is qualitative. The names of U.S. presidents and the states they were born in are the two variables being considered. This means the data set is bivariate.
