Quantitative Reasoning

You will complete this project using the data that you collect from each of your survey participants. Each question has directions to guide you as you reflect on your project and provide answers based on the data you gathered.

Question 1: What are the questions you will be asking participants? ( Same questions approved on your discussion board.)

· Directions: List the survey questions for your statistical study. Be specific about exactly what you will ask people. Also, record the age of each participant. Note: These should be the same questions approved by your instructor from the discussion board.  Carry out the study. Obtain at least 20 participants for your study.

· Tips:

· Choose questions that interest you – something different from the examples provided.

· Avoid simple “yes” and “no” questions without an explanation.

· Have participants expand upon their answers. If they answered yes, why did they do so?

· Record the ages of your participants in a table to keep your data neat!

Question #1:

Question #2:

Question 2: Who is in your sample?

· Directions: Describe who you asked.

Question 3: Who was your intended population?

· Directions: Describe the larger group you are seeking to learn about.

Question 4: Do you think your sample helps you learn about your population? What could you do (if you had more time and money) to gather a sample to better help you learn about your population? Explain in a minimum of 2 sentences.

· Directions: In most cases your sample is probably not perfect. Tell what is good about your sample and how it could have been improved.

Question 5: Using your non-numerical (the question that did not have a number answer) data, make a pie chart or a bar graph.

· Directions: Clearly label the information in the graph and make a descriptive title, so that it is easy for a reader to understand what is being shown. You can do this by hand or using technology. You may need to group similar responses to create a reasonable amount of categories

Question 6: Describe the information shown in the graph.

· Directions: Summarize the data from the shown in the graph you made in question #5. Tell what percentages of respondents fit into each category and describe any interesting, surprising, or noteworthy results. Explore percentages within your data.

Question 7: Using your numerical data (the question with a number answer), calculate mean, median, range, and standard deviation.

· Directions: You can do this by hand or using technology. Show work or include the Excel spreadsheet with formulas.

*Show work for each or include your Excel spreadsheet with formulas

Question 8: Describe the numerical results.

· Directions: Summarize the data. What are your mean, median, range, and standard deviation? Describe these numbers in the context of your question. What does it tell you about the population? What does the standard deviation tell you about how spread out your data is? Do these numbers make sense given real world context?

· Directions: Write a contextualized summary about your data. Explain the graph(s) you created. In words, state what your mean and median values were and what that tells you about your population. State what percentages and ratios you found and what that tells you about your population. Use words from the course (such as majority, plurality, maximum, minimum, mean, median, …) when appropriate. What conclusions can you make? What was interesting or surprising? What additional questions would you ask in a follow-up study?

Choose 2 of the 3 Questions Below to Answer:

· Directions: Connect concepts from the semester to our project! Think critically about how you could apply topics from the semester thus far. Use specific examples to support your answers. 

Question 12: How could you apply the probability concepts learned in lesson 4 to your data?

Give specific numbers from your data and connect to your population. Explain in a minimum of 2-3 sentences.

Rubric Goals: Use these requirements as a guide to ensure that you complete this project to the best of your ability.
