Coaster craze Many people like to ride roller coasters. Amusement parks try to increase attendance by building exciting new coasters. The following table displays data on several roller coasters that were opened in a recent year.

(a) Identify the individuals in this data set.

(b) What are the variables? Classify each as categorical or quantitative.

Short Answer

Expert verified

Part (a) 6 roller coasters.

Part (b) Variables: Type, Height, Design, Speed, and Duration.

Categorical variables: Type and Design.

quantitative variables: Height, Speed, and Duration.

Step by step solution

01

Part (a) Step 1. Given information.

The given statement is:

The table below contains information on a number of roller coasters that have recently opened.

02

Part (a) Step 2. Recognize the individuals under this data set.

Individuals in the supplied data are 6 roller coasters that have recently opened and constructed innovative new coasters to boost attendance.

03

Part (b) Step 1. Identify the variables and classify each.

Variables include:

Type, Height (ft), Design, Speed (mph), and Duration (sec).

Because the categories are wood and steel, the type is categorical.

Height: Quantitative because height has numerical values and listing all conceivable heights is impossible.

Because the categories are sat down and inverted, the designis categorical.

Because speed takes numerical values and it is impossible to specify all potential speeds, it is quantitative.

Because the duration takes numerical values and it is impossible to specify all conceivable durations, it is quantitative.
