ESTIMATING MODELS USING DUMMY VARIABLES
Create a research question using the General Social Survey dataset that can be answered by multiple regression.
(1) Using the SPSS software, choose a categorical variable to dummy code as one of your predictor variables.
Estimate a multiple regression model that answers your research question.
Reply to the following:
(A) What is your research question?
(B) Interpret the coefficients for the model, specifically commenting on the dummy variable.
(C) Run diagnostics for the regression model.
(C1)Does the model meet all of the assumptions?
(C2) Be sure and comment on what assumptions were not met and the possible implications.
(C3) Is there any possible remedy for one of the assumption violations?
Be sure to support your Main Post and Response Post with reference to the week’s Learning Resources and other scholarly evidence in APA Style.

Assignment Scenario
Your community wants to open an adult daycare center. You have located the Farrel Foundation, which would like to fund start-up grants for daycare programs. This foundation’s research demonstrates a correlation between depression and length of time in a skilled nursing facility. A group of community residents feel that an adult daycare would allow the aging population to stay with their families while using the supplemental daycare services. You are asked to confirm the correlation between depression and length of stay in nursing homes in an effort to provide community options. Nursing home residents were asked to complete the Geriatric Depression Scale (GDS), which is a 15-item scale (a 15 represents a high level of depression).
Using the data in the Unit 4 Dataset, given in the resources, test whether length of stay in a nursing home and depression are related at a .05 level of significance.
Also refer to the tutorial provided in this unit’s first study as a reference on how to conduct correlation tests.
Assignment Instructions
For this assignment, respond to the following prompts in a one-page, APA-formatted paper.
Based on the output, state the following factors:
Sample size.
Correlation coefficient.
Significance.
Based on the value of the correlation coefficient, explain whether there is a significant relationship between length of stay and depression.
Based on the correlation coefficient and given the value of r, provide a narrative conclusion:
How might you explain the result of this correlation test?
What other data might you analyze to advocate for an adult daycare in the community, if your finding is not statistically significant?

Hi, I hope you are doing well. May I have your assistance in writing a 500–1000-word research proposal, please? I would like to have a proposal about identification of risk factors that are associated with cardiovascular diseases and mortality and how could predict those factors to prevent both diseases and mortality. Feel free if you suggest another topic!
I would like to have a 500–1000-word research proposal which it must include a well described statistical methodology and must clearly identify the research gap. The proposal should include:
1. Introduction and research gap and a justification why the research question is plausible (150-300 words)
2. Research question and aims (150-200 words): Aiming to investigate the role of various factors (e.g alcohol consumption) in cardiovascular related problem.
3. Methodology (150-300 words): Machine learning approaches (such as neural network and random forest models) to predict a cardiovascular related problem (e.g. stroke, hypertension) and their risk factors (e.g. smoking) using the local city hospital databases.
4. Expected outcomes (40-100 words).
5. Timeline (as a 3-year research) (40-100 words)
References with weblinks. (Number of references does not matter)
Please do not mention related studies of CVD caused by COVID-19 which could cause recourses limitation in future. If you have further questions, please do not hesitate to contact me. Thank you.
Thank you very much in advance!

Please read these. You will build your final paper and presentation in incremental steps starting with a proposal here. You must be detailed in your answer in order to receive full credit. Answer the following questions: 1) What research do you want to do? 2) What sources of information will you use to research your topic (at least three good academic sources). 3) What types of research tools will you use to gather data? 4) How will you measure the data? 5) What do you hope to learn from your research? Minimum 150 words for this assignment.
