You're in a brainstorming session at WidgeCorp, where no idea is too outrageous. You're discussing penetration in the school lunch market. Ideas around school lunch subsidies, Internet subsidies, and Internet target marketing are being discussed. As the end of the meeting, the group asks you to prove or disprove some assumptions by looking at correlations.

First, acquaint yourself with the Internet subsidy issue by reading the article Closing the Digital Divide: Internet Subsidies in Public Schools by Austan D. Goolsbee and Jonathan Guryan (link:http://www.chicagobooth.edu/capideas/summer03/digitaldivide.html)

Prepare a chart similar to the one attached to indicate if the correlation between Variables A and B were found to be positive, negative, or minimal.

In your own words, explain what it means if the correlation of 2 variables is positive, negative, or minimal (close to zero) and give an example of each.

Please research on the Web about the concept of correlation, various types of correlation and its applications including simple and multiple correlation along with examples of its applications and at least three references. Discuss how correlation can be used by WidgeCorp to reach its marketing objectives.
