Section 2 - Describing Distributions with Numbers

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.

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.

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 5 - Sampling Distributions

Section 5.1 - Sampling Distributions for Proportions

Shown above is one of the most well known moments in US Presidential history. The image depicts President Franklin D. Roosevelt delivering 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.

Chapters 6, 7 & 8 - Introduction to Hypothesis Testing

We will begin our discussion on hypothesis testing with a brief exploration of a motivating problem. See the links below.

Yellow Test Versus Green Test

Lab Report Survey


*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.

 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.

EXTRA CREDIT ASSIGNMENT
One of the topics that we have mentioned multiple times this semester is that the interpretation of statistics is an art form. Quite often we find examples in research, the news media, etc. displaying this very fact. The link below is one of those cases. The article posted show an egregious error in the interpretation of the statistics of the poll mentioned by the Gallup Organization. You extra credit assignment is to read this article and the linked article to the Gallup website. I charge you not only to address the errors in the news article, but properly interpret the poll results. Successful completion of this assignment will result in it's score replacing either the lowest lab score or the two lowest hand in assignments (which ever benefits you more). If you plan to attempt this assignment please have it completed and turned in to me by your final exam time.
