Discussion InstructionsrnConsider a measurement (such as a reaction time) that can be taken in your field for each person. Now, consider how you might place people in groups that you would expect to have different values on the measure. Explain how an ANOVA might be used to compare the groups.rnrnWhile you do not have to explicitly respond to the following statements and questions, in order to post intelligently to this discussion, you must understand the concepts they represent:rnrnBriefly explain each of the three different types of t tests, its null hypothesis, and the kinds of data with which it is suitable for use.rnWhat is the difference between a one-way ANOVA and the t test, and how are they related?rnGive an explanation of what a post hoc test in ANOVA is used to determine.

StatisticsYou 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 (uploaded). 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.
