EXAMPLE 1
Crash-Test Results
The data in Table 1.1 are an excerpt from crash-test dummy studies in which cars are crashed into a wall at 35 miles per hour. Each row of the data set represents the observed characteristics of a single car. This is a small sample of the database, which is available from the National Transportation Safety Administration. The head injury variable reflects the risk to the passengers’ heads. The higher the number, the greater the risk.

QUESTION
For each variable, state whether it is numerical or categorical.
