One of the emerging applications we see for statistics is an interdisciplinary journey with the visual arts.  The process for creating informative, descriptive, representative can be daunting and needs proper instruction.

Data Visualization Presentation


Where you get your news used to be a simple question and a simple answer. The local news paper, perhaps the network news that came on shortly after dark. Today, that question is less simple and even more polarizing. Below is a link to the full results of a Public Policy Polling study released on February 6, 2013 dealing with this very issue.

Chapter 3 - Displaying and Summarizing Quantitative Data


Creating films that are "age appropriate" is less of a science and more of an art form. Whereas we might believe a particular film is created to engage a specific audience, raw data of such a showing might prove other wise. Below you will find links to trailers of three different films released in the fall of 2010. Additionally, you will find an excel sheet with some data that I collected outside of the theater.

Hello Kitty Automatic Pistol


Recently, on Capitol Hill, Senator Diane Feinstein introduced new legislation designed to address "Common Sense Gun Regulations". Pictured above is a Customized Velocity Arms Vmac Automatic Pistol that is listed as a proposed "banned firearm". In truth, at the heart of all gun regulation is the hope that we can reduce the overall violent crime rate... So if we are going to speak intelligently about the crime rate, we should at least know what it is and how it works.

Exam 3 Review Documents

Below are some materials that will help you review for this upcoming test.

Chapter 17 - Sampling Distribution Models


One of the most well known moments in US Presidential history was the first inauguration of President Franklin D. Roosevelt. At that moment, President Franklin D. Roosevelt delivered his 1932 inauguration speech titled "The Only Thing We Have to Fear is Fear Itself". As important as this moment was to American history, the days leading up to his inauguration were just as tense and meaningful. Click on the link below to access the electoral map from the 1932 general election.

Exam 4 Review Sheet

Exam 4 Review Sheet Answer Key


Chapter 19 - Hypothesis Testing for Proportions


*5 steps for hypothesis testing*

1. Given a claim determine the null and alternative hypotheses.

2. Given a claim and sampled data determine a test statistic.

3. Given a claim and sampled data find a critical value.

4. Given a claim and sampled data find a p-value.

5. State your conclusions in plain understandable English


Below is a link to the PDF of your next project assignment.  This same assignment has been shared to your google drive.  Please answer each question on the shared google drive document no later than Thursday, November 9.

 Introduction to Hypothesis Testing


Since the nuances of hypothesis testing are to say the least, complicated, it is reasonable to believe that conclusions based upon these tests must be worded properly. See the following link for hints on how to do this.

Wording of the Final Conclusion
