1.1 Four different beverages are sold at a fast food restaurant: soft drinks, tea, coffee, and bottled water.
Explain why the type of beverage sold is an example of a categorical variable
Explain why the type of beverage sold is an example of a nominal scaled variable

Categorical variables take values that fall into one or more categories. "Categorical variable is defined as data divided in categories as yes or no"(Chapter 1 ­ Statistics for Manager 7th Edition).
