You are in a brainstorming session at WidgeCorp
You are in a brainstorming session at WidgeCorp, where no
idea is too outrageous. You are 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.
Next, download the file Sample Data. Based on the findings
as reported in this article, prepare a chart similar to the one in the
downloaded file 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 0), and give an
example of each.
