This page explains the assignment. The questions you need to answer are on the next page.

A key part of research involves formulating interesting questions and then developing a methodology and collecting appropriate data to answer those questions. In this assignment, assume that you are the researcher who developed the survey you saw Part A of this assignment. Normally, you would have your research questions in mind prior to developing a survey. We will “pretend” that was the case, but in reality, the first thing you need to do to complete this assignment is to formulate questions that can be answered based on sample data you collected  in Part A. For convenience, the survey items are shown below.

 

Here are some questions (from the StatCrunch website) that could be answered using survey data:

 

The items below ask you to formulate a question, describe your methodology for answering the question, carry out the methodology you described, then answer your question. Although not as detailed, this mirrors the format used in many research reports.

 

Respond to the following items.

 

  1. In Part A of this assignment, you selected a random sample of 30 StatCrunch U students and created a StatCrunch file containing data from the above survey for those students. You will use the StatCrunch data file you created in Part A to complete this assignment. Following the instructions at the end of Part A, paste your StatCrunch data file in the space below. This will allow your instructor to see your data.

2a. State a question related to a categorical variable that can be answered using your survey data and the techniques you have studied thus far in this course. You are encouraged to develop your own question, but you may use an appropriate question from the StatCrunch website. The question you use should be about the entire population of StatCrunch U students—not just about those in the sample. Assume that your sample is representative of the population.

 

 

  1. Explain the methodology you will use to answer the question you posed. Your explanation should include answers to the following questions. Do not include your analysis or answers to your question here—only describe how you will do the analysis.

 

  • What is the variable of interest?
  • What graphical techniques will you use to describe your data?
  • Why are those techniques appropriate? Why did you choose them?

 

 

  1. Carry out the methodology described in b above. Use StatCrunch and paste copies of the graphs/charts from StatCrunch in the space below.

 

 

  1. Based on the results of b and c above, answer your question. Include an explanation of how you used the graphs and charts to formulate your answer.

 

 

 

3a. State a question related to a numerical variable that can be answered using your survey data and the techniques you have studied thus far in this course. You are encouraged to develop your own question, but you may use an appropriate question from the StatCrunch website. The question you use should be about the entire population of StatCrunch U students—not just about those in the sample. Assume that your sample is representative of the population.

  • Why did you choose them?
  • What numerical measures will you use to describe your data?
  • Why are those measures appropriate? Why did you choose them?

 

 

  1. Carry out the methodology described in b above. Use StatCrunch and paste copies of the graphs/charts and numerical summaries from StatCrunch in the space below.
