# Youre in a brainstorming session at WidgeCorp, where no idea

### Customer Question

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 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. 400-600

Positive Correlation - the relationship between two variables is such that as one variable's values tend to increase, the other variable's values also tend to increase. This is represented by a positive correlation coefficient. Example would be - the more games a basketball team wins, the more points they get.

Negative Correlation - the relationship between two variables is such that as one variable's values tend to increase, the other variable's values tend to decrease. This is represented by a negative correlation coefficient. Example would be - the more cats out there, the fewer mice one would have in the barn.

Minimal Correlation - the relationship between two variables is such that as one variable's values tend to change, the other variable's values change insignificantly compared to the first variable. Example would be - even if the gas gets cheaper, we are not going to have significantly more buses on the streets, since the city doesn't have that many of them.

Widge Corp. could use correlation to figure out if the schools receiving funding would be willing to buy lunches from them. On the other hand they could compile a report to convince other schools to buy their lunches as that would allow them to get subsidies from the government.

Here is a word document with the chart and whats above.
