Quantitative Project: Introduction

Due: Wednesday
Points: 5

This is a multi-seminar small scale research study project beginning in Seminar One and ending in Seminar Five. Here is a snapshot of what is in each seminar. For the full overview, click on the link: Complete Quantitative Project

• Seminar 1: Quantitative Project: Introduction
• Seminar 2: Quantitative Project: Design of Project
• Seminar 3: Quantitative Project: Data Collection
• Seminar 4: Quantitative Project: Analysis
• Seminar 5: Quantitative Project: Final Presentation

Introduction

To begin the project, you will choose a topic of interest. This topic can be from the news, in your field of study, or just something that interests you.

From this topic, choose two variables that you can test to see if there is a relationship. The variables must be measurable (quantitative, see P.7). Please note that once you submit your topic, it must be approved before you can continue to the second part of the project. 

The following is an example to illustrate a topic of choice: You may want to stay in shape physically. You could use time exercising (x) and weight (y) for the variables. You are hypothesizing that time working out and weight are negatively correlated. This is, the more you exercise, the less you weigh. This is just one example to get you thinking!

In a Word document, submit the following:

• Your topic of interest with an explanation of why you are interested in this topic.
• State the goal of your study clearly. Include an explanation of what you are trying to determine with the data you are going to collect.
• Use APA font style, 12-pt. font and cite all resources in APA.

Once you have received feedback from your instructor, you can proceed onto the second part of the project.

• StatCrunch 1
• Due: Wednesday
  Points: 5
  1. Mean, median, and mode (1 point)
  2. Standard deviation (1 point)
  3. Five-Number Summary (1 point)
  4. Finally, create a horizontal boxplot using fences to identify outliers. Is there an outlier in this data? If yes, what is it? (2 points)

  Copy and paste your StatCrunch tables and boxplot into a Word document. Click on the assignment title link to upload your work as an attachment. Do not copy and paste your work into the text box. Per Baker policy, .doc or .docx files will be the only format accepted. No scanned work is accepted and you must type your assignment. 

• In StatCrunch, using the data set 3.5.14a from the text, calculate the following:
• Case Study
• Due: Wednesday
  Points: 40Create a report that graphically displays and discusses the tornado-related data. Your report should include the following:
  1. A bar graph or pie chart (or both) that depicts the number of tornadoes by F-scale. Generally, only a little more than 1% of all tornadoes exceed F-3 on the Fujita Wind Damage Scale.
     1. How does the frequency of the most severe tornadoes of the April 3– 4, 1974, outbreak compare with normal tornado formation?
  2. A single histogram that displays the distribution of tornado duration for all the tornadoes.
  3. Six histograms displaying tornado duration for each of the F-scale categories.
     1. Does there appear to be a relationship between duration and intensity? If so, describe this relationship.
  4. A bar chart that shows the relationship between the number of deaths and tornado intensity.
     1. Ordinarily, the most severe tornadoes (F-4 and F-5) account for more than 70% of deaths. Is the death distribution of this outbreak consistent with this observation?
  5. A bar chart that shows the relationship between the number of deaths and community size.
     1. Are tornadoes more likely to strike rural areas? Include a discussion describing the number of deaths as a function of community size.
  6. A general summary of your findings and conclusions.

• (SLOs 2, EOs 2b, 2d-e)
• Your textbook came with a CD ROM with case studies. You can also find the case studies at the end of each chapter in the eBook through MyLabsPlus. Complete the Chapter 2: The Day the Sky Roared Case Study. After you have read the study and analyzed that data within the tables, complete the following:
• Seminar One Quiz
• Due: Wednesday
