Data & Statistics Projects Project 1 Data Gathering & Presentation |
Project 1 Report
Group Expectations
Meetings: Each group should meet at least twelve hours before each report is due.
1st Draft: Before meetings and at least 48 hours before the report's due date on the syllabus, each group member should post a draft version of their part of the report in their D2L group discussions. Before meetings and at least 36 to 24 hours before each report is due, the group leader should post to the group project's dropbox a draft of the entire report. All group members will be responsible for grading the dropbox-posted project with the rubric and editing the project whenever the rubric is not met. The group should go through the entire report, discussing each part and matching each part to the rubric. Each group member is responsible for the accuracy of all calculations; the clarity, completeness, and accuracy of the answers to all questions; and the overall report presentation, style, and quality. If any group member feels a part of the report does not meet rubric specifications, is incorrect, or is lacking in any way, that part of the report should be discussed and revised by the group at this group meeting.
Evaluate your peers by submitting one peer review for each member of your group. Individual grades will greatly depend on turning in your own evaluations by the due date and in the evaluations of you by fellow group members.
The group leader will immediately (within 2 to 3 days of each previous project or pre-project being due) assign all parts to the various group members, keeping the Wrapping It Up part for himself or herself and splitting the remaining parts as equally as possible based on the point distribution in the rubric and the part divisions already assigned in the project description. The group leader is responsible for ensuring group members post their respective assigned parts of the project at least two days prior to the project due date - or even earlier if the leader specifies an earlier time when assigning parts, at the leader's discretion. If a group member is late, the leader will reassign that member's part to active group members and will let the instructor know immediately.
Other members will be responsible for completing all assigned parts at least two days prior, or even earlier, if specified, and posting those parts to the group discussion board. If the group leader has not assigned roles for the project within two to three days of the previous project or pre-project being due, then the group contact the instructor know immediately. Any student who does not understand completely his or her assigned part should immediately ask for clarity and help from group members. Any member turning in his or her part late may receive a zero for the current project if this part was assigned and completed by another member because of the lateness.
Report Expectations
In formal, professional reporting style, the full report for Project 1 needs to be written to include everything in Questions 1 through 16, although the questions and question numbers should not be included. This report should read as if the reader has no knowledge of these questions nor any knowledge that the questions have prompted the writing of the report. The entire report should be in complete sentences and full paragraphs with the exception of tables, charts, graphs, equations, and lists of statistics. Everything from formatting to grammar to style should be as professional as possible.
To be successful with this project, students should:
PART A: Gathering - The Sample and Design
Once your pre-report is submitted, you can start working on the full report.
1 - Detail how you conducted the survey, including who, when, and where. Exact dates, times, and locations should be given for each survey collection. Of the group meeting for Project 1, tell when, where, who met, and for how long.
2 - Organize all collected data into a table with columns as the questions, rows for each anonymously numbered survey participant (at least 30 total), and with cells containing that participant's answer to that question. This table should be in the appendix (the very end, after the body) of the paper.
3 - Answer the following questions clearly so that your answers cannot be misunderstood and so that the reader will not doubt which question you are answering:
PART B: Organizing and Presenting Quantitative Data (Use Your First Quantitative Variable)
4 - Collect and organize the raw data for the first quantitative variable into a frequency distribution table using Microsoft (MS) Word's Insert Table feature.
5 - Create a labeled histogram of your first quantitative variable data using the MS Word Chart feature. (Here's a video showing how to create a histogram in Word on a Mac, and the process is fairly similar on the PC.)
6 - Calculate and report the following descriptive statistics for the first quantitative variable: mean, median, mode(s), standard deviation, range, all of the quartiles, and IQR of your data.
7 - Create a boxplot of your first quantitative variable data using the MS Word drawing tools (Insert Shape) to draw the boxes, lines, and whiskers as well as the number line (axis).
8 - Describe the distribution of the first quantitative variable, including:
a. modality,
b. skewness (best judge is whether mean is less or more than median), and
c. symmetry.
9 - Which measure of central tendency (mean, median, or mode) do you think best describes the first quantitative variable data? Why?
PART C: Organizing and Presenting Categorical Data (Use Your First Categorical Variable)
10 - Collect and organize the raw data for the first categorical variable into a frequency distribution table.
11 - Create a labeled pie chart of your first categorical variable data using the MS Word Charts feature.
12 - Which measure of central tendency (mean, median, or mode) do you think best describes the first categorical variable data? Why?
PART D: Analyzing the Association between Two Quantitative Variables
Choose two quantitative variables that you believe may be associated with each other. Ask yourself which variable more likely explains (explanatory variable) the other, and which variable more likely responds (response variable) to the other?
13 - Using explanatory variable as the x-variable and response variable as the y-variable, develop a linear regression equation.
14 - Use the linear regression equation from the previous problem to predict the response variable when the predictor (explanatory) variable is 0. (If 0 is an unreasonable value for your predictor, choose a different, reasonable value but clearly state what you are using as the predictor.) Is this prediction extrapolating? Why or why not?
15 - Do you think your linear regression equation is a good equation for predicting the response variable? What statistical evidence supports your answer? (HINT: There is one statistical measure we compute that tells us the strength of the association and hence the strength of the evidence that the linear regression equation is a good predictor. You should report and use that measure to determine if your equation is good. WARNING: This question has nothing to do with extrapolating. Assume you are in the range of your data so that extrapolation isn't an issue.)
Wrapping It Up
16 - Have a paragraph at the end detailing what exactly each group member did to contribute to the entire group effort.
You will want the document to have a title page with a title for the paper, Math 1530, the date, the name of the group, and a list of the group members. You will want to add the histogram and pie chart (and any other images) by creating them in the body of the report using Microsoft Word, as mentioned in the video above.
Save your MS Word document as Project1_GroupName.doc or Project1_GroupName.docx.
Load the file to the dropbox. Open the file straight from the dropboxes so that you can grade the file that is in the dropbox. Print the group project rubric and grade your report, correcting anything in the report that fails to fully satisfy the rubric.
After grading and correcting your report, load the report to D2L's Project 1 dropbox. Every single group member needs to reopen the MS Word report straight from the dropbox to make sure that all sixteen questions are answered and that this report is the latest, best edited version. Every single group member will be held responsible for making sure that the report rubric.
Evaluate your peers by submitting one peer review for each member of your group. Individual grades will greatly depend on turning in your own evaluations by the due date and in the evaluations of you by fellow group members.
