**Question description**

**Week 2 -Assignment**

**I just need the week 2 Assignment Part**

Descriptive Data Analysis

Review the instructions for your Final Paper in Week Five of the

course. For this week’s assignment, utilize the following Excel data, which contains

B.M.I., F.B.S., gender, and clinic information for a group of children ages

10-14, to complete the first item of your Final Paper.

The first step in any research study is descriptive

statistics. Describe the study participants in terms of gender,

clinic where data was collected, B.M.I., and F.B.S. Present the

descriptive analyses for all the variables (with the exception of I.D.

#). Explain why each descriptive analysis was chosen. Use the

Descriptive Statistics option in Excel for continuous variables. Use

appropriate charts. Utilize the Excel pivot table/pivot chart and

the How to make a frequency

distribution table for nominal data in Excel instructions for

nominal variables. Interpret your results.

Week 5 - Final Paper

Final Paper

For your Final Paper, you will apply the knowledge and skills acquired

throughout the course to analyze and interpret a dataset containing

health-related variables to answer health research questions.

Due to the current increase of

diabetes in children, studying factors that affect its occurrence and evolution

is very important. Obesity is one of the key factors affecting childhood

diabetes and health practitioners frequently use the Body Mass Index (B.M.I.)

to assess whether or not a child is obese. In the attached Excel document, you will find

data on the B.M.I., fasting blood sugar levels (F.B.S.), gender (Male or

Female), and the clinic where this information was collected (clinic A, B, or

C) for a group of children age 10-14. The purpose of your study is to

analyze any possible relationships among the given variables. There are

three tabs at the bottom of the Excel file which represent different data set

pages: “All Variables”, “B.M.I. of Boys and Girls”, and “F.B.S. by

Clinic”. The “All Variables” page is formatted the way you would

typically see this data displayed in current data analysis. The first

column represents the subject’s I.D. number, the second column denotes gender

(M/F), the third is B.M.I., and the last is their F.B.S level. Each row

corresponds to a child in the dataset, with his/her corresponding

characteristics. For example, the study participant with the I.D. number

10 is a boy (Gender=M), who was assessed at clinic B, has a B.M.I. of 28 and an

F.B.S. of 92.

Any statistical analyses needed for

this paper, including the corresponding Excel steps and procedures, are

explained in your course text with the exception of providing descriptive statistics

(frequencies) for nominal variables. Descriptive statistics procedures

for continuous variables are included in Chapter 1 of your course text.

Instructions and information on descriptive statistics (frequencies) for

nominal variables are provided in the How to make a frequency distribution

table for nominal data in Excel resource.

Your Final Paper must contain the following:

The first step in any research study is descriptive

statistics. Describe the study participants in terms of gender,

clinic where data was collected, B.M.I., and F.B.S. Present the

descriptive analyses for all the variables (with the exception of I.D. #).

Explain why each descriptive analysis was chosen. Use the

Descriptive Statistics option in Excel for continuous variables. Use

appropriate charts. Utilize the Excel pivot table/pivot chart and How to make a frequency

distribution table for nominal data in Excel instructions for

nominal variables. Interpret your results.

- Assess how B.M.I. varies by gender. Use the tab

“B.M.I. of Boys and Girls” in this Excel document.

These are the same study subjects described in the “All Variables” tab,

but the data on gender and B.M.I. is set up in a way that will facilitate

running the statistical analysis to assess whether there is a difference

between the B.M.I. of boys and girls. What test will you use? What

does the test reveal? - Analyze F.B.S. by clinic. There are three clinics

(A, B, C) and data is ready for your analysis in the “F.B.S. by Clinic”

tab of this Excel document.

What statistical analysis is most appropriate? Why? What do

the results indicate? - Correlate F.B.S. with B.M.I. What correlation

coefficient will you use? Why? Report the correlation coefficient

and explain whether this is a statistically significant correlation.

Explain what it means for two variables to have a statistically

significant correlation. The steps for running a correlation in

Excel are described in Section 8.4 of your course text. - Run a simple linear regression predicting F.B.S. from

B.M.I. Report your results. Does F.B.S. increase or decrease

with B.M.I.? What components of the output do you read and interpret

to answer this question? Write the regression equation and include

it in your paper. The steps for running a linear regression in Excel

are described in Section 9.3 of your course text. - What analysis would you employ to determine whether

boys and girls were assessed in similar proportions in each of the three

clinics? Explain and justify your choice. You do not have to

run this analysis; just identify the one you would choose. - Multiple regression is a form of multivariate analysis

and constitutes a way to accommodate multiple predictors of one dependent

variable, considered all at the same time. It is used commonly in

health research as a*control*for other variables when researching

the effect of one variable of interest. It is also frequently used

to explain more variance in the dependent variable. What additional

variables would you want to control when predicting F.B.S. from B.M.I.?

These can be variables in your dataset or other variables you think are

relevant that are not in your dataset. Identify at least three

control variables. Why did you select these three in

particular? - State your conclusions and formulate a discussion of

your findings. Would you like to know anything else about this

participant sample? What further research would you do?

Why? Refer to glucose levels, diabetes, other related variables, and

available research on the topic of diabetes in children as well as the

analyses that you performed. Support your response with at least two

to three scholarly, peer-reviewed articles.

*Writing the Final Paper*

The Final Paper:

- Must thoroughly and completely address all questions

and requirements listed above. Graphs, tables, outputs, and

equations should be included. They must be clearly titled and

explained. To show your outputs, simply copy and paste your results

from Excel into the assignment Word document. - Must be a minimum of eight pages in length (excluding

title and reference pages). Your assignment will be assessed based

on how well you have answered the components of each of the eight

questions above. - Must be formatted according to APA style as outlined in

the Ashford Writing Center. - Must include a title page with the following:
- Title of paper
- Student’s name
- Course name and number
- Instructor’s name
- Date submitted

- Must address the topics with critical thought.
- Must use at least two to three scholarly,

peer-reviewed, articles which are required to answer Question #8. - Must document all sources in APA style and include a

separate reference page, formatted according to APA style as outlined in

the Ashford Writing Center.

Carefully review the Grading Rubric for the

criteria that will be used to evaluate your assignment.
