MATH 175 Homework 1

Due in Class 5/19/16

Read chapters 1 and 2 in the book.

1. You are being hired as a consultant for Crazy Mocha to provide statistical evidence on where to buy property for a new franchise location. You will have to come up with different statistical studies to support your results. Obviously, a lot of money and your credibility rely on the accuracy of your results. I want you to create three statistical studies for Crazy Mocha. Describe how you will collect your data or survey members of your community. Describe the type of data you will need for your tests. Describe any possible confounding variables in your study and how you will mitigate bias in your results. Finally, how would you present this data? What types of visual representation will be useful to present your results. I am looking for a paragraph or two to describe each test.

2. Tableau is a software used to create great visuals for statistical data analysis. Many companies buy this software to present visual data analytics for their audiences. I would like you to download the free version of Tableau and create 10 different data visuals describing your data in some way. Play around with the different tables and charts in the package. For your homework, do not just provide me pictures. Give me the visual and describe what you are providing. This can be summed up in a sentence or two. You can find sample data at the link in the Homework Folder. Feel free to use one or more data sets. Tableau Desktop can be downloaded at the site given in the Homework Folder. You will have a free trial for 15 days; this is fine as we won’t use this again after the first homework. I have some example Tableau Visuals in the Homework Folder. You stuff does not have to be as crazy as what I provide, I just want to show you some things others have done and what is possible. Stats goes beyond your basic histogram and pie chart.
