Use the Excel spreadsheet “BRFSS” and the “BRFSS Dataset Codebook” on D2L to answer the following questions. Provide the output tables and codes for this assignment along with this sheet. You may also combine them into this document (by copying and pasting figures and code).

Data Description

1. How total many cases (observations) are there in this data set? How many males and females are there (variable “SEX”?) Remember that RStudio is case-sensitive. (2 points)

2. a. How many of the total cases reported “excellent” and “poor” general health (variable “GENHLTH”)?
b. How many of the total cases performed physical activities in the previous month (variable “EXERANY2”)? (3 points)

3. How many total cases were ever told that they had diabetes, including women who were told during pregnancy (variable “DIABETE3”)? (2 points)
table(BRFSS$DIABETE3)

4. What are the income level categories (variable “INCOME2”) by sex (NOTE: Only report those for the following categories: “<$15,000”; “$15,000- <$25,000”; “$25,000- <$35,000”; “$35,000- <$50,000”; “$50,000 or more”. Only include categories 1 to 5. Do not report income categories labeled: “6”, “7”, “8”, “77”, “99”)? Which sex had a greater proportion making $35,000 – <$50,000 annually? (3 points)

Finding Descriptive Statistics

For the remainder of this assignment, you will need to use the Excel spreadsheet “NHANES” and the “NHANES 2013-2014 Data set codebook” on D2L to answer the following questions. Provide the output tables and codes for this assignment along with this sheet. You may also combine them into this document (by copying and pasting figures and code).

5. Without calculating significant differences, which educational level (variable “educ_adult”) has the highest average (mean) systolic (variable “AVGSBP”) and highest average (mean) diastolic blood pressure (variable “AVGDBP”)? (2 points)

6. What are the 25% (1st Quartile), 50% (Median), and 75% (3rd Quartile) quantiles for calcium? (3 points)

Calculating t-tests

7. Is mean systolic blood pressure (variable “AVGSBP”) different between males and females in the sample? To answer that question, you need to complete the following sub-questions. (10 points)
a. First, what type of t-test would you use?
b. What type of homogeneity test do you need to run before you can run your t-test (also provide the code for that test and corresponding output)?
c. Are there equal or unequal variances? Based on results from the aforementioned test, would you run a normal two sample t-test or a Welch two sample t-test?
d. Now run your t-test and answer the question. Provide the code, output, and interpret the results.

8. Is mean sodium (variable “sodium”) intake different between males and females in the sample? To answer that question, you need to complete the following sub-questions. (10 points)
a. First, what type of t-test would you use?
b. What type of homogeneity test do you need to run before you can run your t-test (also provide the code for that test and corresponding output)?
c. Are there equal or unequal variances? Based on results from the aforementioned test, would you run a normal two sample t-test or a Welch two sample t-test?
d. Now run your t-test and answer the question. Provide the code, output, and interpret the results.

The structure I request as Following :
1-Introduction.

2-Research Objective and Aim.You have to write What is the goals of the research.

3-Research Questions.Please see my research questions in my old proposal attached .you have to write 4 questions For example :What is the key factors promoting diversity management in Aviation industry in Saudi Arabia?

4-Methodology. What method of data analysis will you use and why will you use that one.What type of data will you collect (and why) . Where do you proposed to do the study .
Please note, in Methodology you can use same Method on my previous Proposal but remember I am going to talk about different topic.

5-.Significance of the research. You Have to explain Why it is important to undertake this research,

6-Literature review. In the literature review you have to follow this step:(1) Choose a theory that is used in your area of interest.
(2) Talk about the theory – how it was developed, why it was important.What Authors proposed.put a references at the end.
(3) Identify a gap in theoretical knowledge (for example, not enough research has been done that examines X).
(4) State how your dissertation will address the gap you have identified by examining management of diversity policy in the aviation industry in Saudi Arabia.

7-References

Please do heading on each part exactly the same my previous proposal .
Please note if this order meet my requirements I will give you a very positive feed back plus i will send you another assignment.

inferential techniques within EXCEL to analyse business data.the work must be done in excel but you have to transfer everything over to word. Make sure you present your findings in Word in a nice format. The last page or two of the assessment brief explains this in detail.

I will take care of Coursework 1, where I need to do a computer based test. Your task is only to take care of CW2. I will upload guidelines as well as the assessment brief of this module. There you can find the instructions for CW2 beginning from page 8, if you have any questions please let me know, many thanks for your help, may god bless you, regards, dardan

Data Analysis Report Coursework 2: 60% weighting o Assesses learning outcome 1 and 2 o This comprises the application of descriptive and inferential techniques within EXCEL to analyse business data

For CW2, the assignment, you are asked to calculate several statistics, such as the mean, the variance, or draw several graphs, such a stem and leaf diagram, a dot plot, etc.
For full marks it is not enough to simply give me the numbers EXCEL calculates for you or to simply give me the graph. You need to be able to explain what the mean is, what the variance is, and why we use them, etc. This has to be done for all calculations and graphs. Explain what they are and why we use them.

For example, let’s say you calculate the mean to be 50. If you simply write “Mean = 50” in the assignment you will not be awarded full marks. You need to be able to explain what the mean is, why we use it, what are its advantages and disadvantages, and then tell me the number “50”. You may also discuss what this “50” actually means.
The point I would like to make is that I would like to see that you understand, thoroughly, what each measure is and why we use it, and what kind of information it provides.

The reason you will not be awarded full marks for a simple “Mean=50” is that the calculations are being done by Excel so in essence, by simply relaying that information, you are not showing any signs of learning.
In short, write as much as you can. There is no word limit.

My apologies for this but a fellow student asked me how I would like to receive the results of CW2 since the work is in Excel.

Yes the work must be done in excel but you have to transfer everything over to word. Make sure you present your findings in Word in a nice format. The last page or two of the assessment brief explains this in detail.

In short do your calculations in Excel but present everything in a nice formatted way in Word. This is what expected by your future employers, a nice, readable, summary of your findings.
