Reasoning with Statistics course information

MyMathLab is a required resource for this course. You may purchase access through the ASU bookstore or you may purchase access online. I realize that the cost is great, as such you may register for a 14 day trial period for access. Below are the instructions for registering for your MyMathLab section.

Introductory Survey / Introduction to MyMathLab

Click on the link below to complete the introductory survey. Please be aware that although the identity of the respondents will be kept anonymous, the results will be available to all students.

Once you have completed the introductory survey, you will want to familiarize yourself with the MyMathLab Learning Management System. We will be using this online portal to access Statcrunch, the electronic version of your textbook, and the MyMathLab portion of your graded assessments. Click on the link below to take you to the MyMathLab Login Page.

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.

Chapter 4 - Understanding and Comparing Distributions

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.

Project 1

Below are two links: the first is to a word document that details the assignment description and the second is an excel document that contains the data you are asked to analyze. These same two documents have also been added to a google drive folder linked under your personal ASU account. Please submit your work using the document provided in drive. Please see this link for further instructions on submission. Please complete this project assignment no later than Monday, February 5 by 11 PM.

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.

Posted below are a few questions I would like you to ponder with a nearby classmate.

As you all know, we are quickly approaching our fourth test date. The link below provides you access to an exam that I gave in a previous semester. This should help you with your preparations for our next test.

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

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

PROJECT 4

I have created a 4th project for your consideration based on the first few steps of the hypothesis testing process. You will find this document in your google drive account. Please complete this assignment no later than 11 PM on April 18, 2018. Good Luck!!!
