Before we pursue this specific question, let's look at an extreme hypothetical example.
Consider Table 44.1. It tells us the number of bedrooms and bathrooms of new houses being built in the community along with the list price for each. There are many houses, but they are all one of the three types and they are all priced very close to their respective list prices.
Table 44.1 House features and prices.
|(Number of bedrooms)||(Number of bathrooms)||(House list price)|
