STAT 512 Assignment

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
sawPart A of this assignment. Normally, you would have your research questions
in mind prior to developing asurvey. 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

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.

Below is the data needed (completion Part A)

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.

b. 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?

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

d.
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.

b. Explain

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

c.
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.

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