Write
a 750-1000 word statistical laboratory report using the guidelines in the
assigned article, “How to Write a Statistical Report.” This
statistical report is not meant to be an APA report or a multiple-page
scholarly treatise. The goal is that you become familiar with the formal report
format that you will use whenever you are reporting statistical analysis. The
report format includes the following sections: Abstract, Purpose, Methods, and
Results.

Assume
that you are asked to perform an exploratory data analysis in which the
emphasis is to compare the difference between the body mass index (BMI) values
of men and women. Use Excel and/or SPSS to create reports and run analyses on
the data for the Data Set 1 in Appendix B of your textbook.

Assume
you are a biostatistics analyst and you received a request from the director of
the nutrition program to perform the analysis. The director is developing an
obesity program for the state and has obtained the data set from the National
Center for Health Statistics (NCHS). Because it has been some time since the
director has had a statistics course, any points that would make your analysis
easier to understand would be appreciated.

Generate
appropriate histograms or box plots. Find appropriate statistics that will help
to understand the data set. Are there any notable features? Are there any
outliers? Describe the key elements of center, variation, distribution, and
outliers.

A
minimum of three scholarly references are required.

While
APA format is not required for the body of this assignment, solid academic
writing is expected, and in-text citations and references should be presented
using APA documentation guidelines, which can be found in the APA Style Guide,
located in the Student Success Center.

This
assignment uses a grading rubric. Instructors will be using the rubric to grade
the assignment; therefore, students should review the rubric prior to beginning
the assignment to become familiar with the assignment criteria and expectations
for successful completion of the assignment.

You
are required to submit this assignment to Turnitin. Refer to the
directions in the Student Success Center.

Rank Correlation

Details:

For
the following assignment, use the Rank Correlation that was demonstrated in
Chapter 12 of the textbook (page 566). Utilizing Excel or SPSS:

1.
Use a rank correlation coefficient to
test for a correlation between two variables.

2.
Use a significance level of ?=0.05.

The
new health care program in the United States makes provisions for capitation
programs where health care insurers work with clinical facilities to perform
risk analysis of patients to determine the cost of providing care. The
following assignment might be used to assess how much a person smokes.

When
nicotine is absorbed by the body, cotinine is produced. A measurement of cotinine
in the body is therefore a good indicator of how much a person smokes. The
reported number of cigarettes smoked per day and the measured amounts of
cotinine (in ng/ml) are provided. (The values are from randomly selected
subjects in a National Health Examination Survey.) Is there a significant
linear correlation? How would you measure the cotinine level in the body?
Explain the result.

Refer
to the “Rank Correlation Table.”

APA
format is not required, but solid academic writing is expected.

You
are not required to submit this assignment to Turnitin.
