Statistics Question

MAT 152 Signature AssignmentThe purposes of the project are to distinguish between quantitative and qualitative data, to demonstrate both an
understanding of the appropriate means of displaying, analyzing and interpreting statistics on each type, and the
appropriate use of technology to produce a report of the findings.
Project Outline
1. Pick a meaningful survey topic that can be investigated by asking people in your surroundings (students, coworkers,
neighbors, etc.). Identify and explain how the sample was selected. You must survey at least 30 people.
2. Your survey must contain 3 questions:
a. 1 question that has a qualitative (word) response. The question needs to have at least 4 responses. Yes/no
questions are not accepted.
b. 2 questions that give a quantitative (numeric) response that you think may have a relationship.
3. You must get your instructor to approve the survey.
4. Collect and compile the data.
The report you submit must include the following:
5. An introduction, explaining what topic is being investigated and how the survey was conducted. Identify and explain
how the sample was selected. Is it biased?? If so, why? How could you have taken a better survey?
Include a screenshot of your data editor screen to show your inputted survey data.
6. Important: Using SPSS, (Strongly suggest printing labs 2 through 6 for guidance.)
a. For the qualitative data
1. Create a frequency table
2. Create a pie chart and a Pareto chart
3. Write a conclusion. This should include but is not limited to discussing the qualitative data charts and
graphs, stating the mode, and any interesting finds in your data.
b. For the quantitative data. Pick one of your quantitative data variables and create the following tables/graphs.
1. Create a histogram using between 5 and 10 classes (Visual Binning).
2. Create a dot plot.
3. Calculate the mean, median, mode, range, standard deviation, and five number summary.
4. Create a box plot.
5. Identify any outliers.
6. Write a conclusion for this section of your data. This should include answering the following. What is
your mean and median? Based on this information is your graph skewed? Do you have any outliers,
state the value of the outliers or state that no outliers were noted, and state if you were surprised by
the outliers? What other outcomes did you find interesting from your graphs/charts.
c. Using both of your quantitative questions, (using lab 6 as your guide), create/answer the following:
1. Determine which one you believe to be the explanatory variable and which is the response variable.
2. Construct a scatterplot
3. Graph the best fit line on the scatterplot (If you are unable to get a best fit line, you need to go back
to lab 2 and fix the measurements for your quantitative variables. If the variable is quantitative
remember it must be set to scale. If this happens you may have to start this section over again.)
4. Find and interpret the correlation coefficient
5.Determine the regression equation of the best fit line.
6. Find and interpret the slope.
7. Find and interpret the y-intercept. Discuss whether the y-intercept makes sense in context.
8. Write a conclusion. This should include but is not limited to stating the explanatory and response
variables, stating whether there is a linear correlation and what that r value is, and whether that is what
you expected. Also state what the least squares regression line is and explain the meaning of the slope
and y-intercept mean in this situation. Also interpret the y-intercept or explain why it could not be
possible. State other things that you found interesting from the results of your two quantitative
questions. Make a prediction about what you expect to happen in the future based on your results.
Lastly, if you were to do this project over again, would you do anything differently?
How to Submit Your Signature Assignment:
1) Open a new Word document.
2) Click on the magnifying glass at the bottom of your screen
3) Type in Snipping Tool.
4) Use this tool to highlight and copy each chart on to your word document.
– Only copy the charts listed in the Signature Assignment. Do not copy any of the coding from SPSS.
5) Once all charts are in the word document, you can add your Introduction, conclusions for Part A, B, and C, and
finally answer questions for Part D from the chart on the SA.
6) Save final Word Document and submit in BrightSpace.
