College admissions data

A social scientist wants to study effects of the number of media outlets and universities and the literacy rate on the college admissions of the population. For 10 cities around the world, the scientist determines the number of newspaper copies, radios, and television sets per 1,000 people. The scientist also records the literacy rate and whether a university is in each city. The scientist wants to reduce the total number of variables by combining variables with similar characteristics.

You can use this data to demonstrate Cluster Variables.
