Select a peer-reviewed journal article about a quantitative research study related to human services management that is also related to the Research Proposal topic selected by your Learning Team. Make sure the article includes information on statistics.

MTH156 CSU Global Math Unique Normal Distribution Curve Worksheet

When one thinks of the normal distribution, the first thing that comes to mind is the bell curve and grades. While this is one example of a normal curve that is widely recognized, it is not the only one. Come up with a unique normal distribution curve. Explain your normal curve with items such as the mean and standard deviation. What do the areas in the intervals µ – σ to µ + σ, µ – 2σ to µ + 2σ and µ – 3σ to µ + 3σ represent as far as areas under the normal curve? With the mean and standard deviation, calculate what the actual intervals are for your normal curve. Please include any citations regarding where you obtained the data for your curve.

Hypothesis Testing

In hypothesis testing we set alpha, the significance level, which limits the likelihood of making a Type 1 error if the null hypothesis were true. When does a type 2 error occur? Give a real world example of a decision and explain what the null hypothesis, alternative hypothesis, type 1 and type 2 errors would be – which would be worse in this case: making a type 1 error or making a type 2 error?

STA3215CBE Rasmussen Critical Regions & P Values Population Parameters Paper

Competency

Formulate and evaluate hypothesis tests for population parameters based on sample statistics using both Critical Regions and P-Values, and be able to state results in a non-technical way that can be understood by consumers of the data instead of statisticians.

Student Profile

You are a statistician working for a drug company. A few new scientists have been hired by your company. They are experts in pharmacology, but are not experts in doing statistical studies, so you will explain to them how statistical studies are done when testing two samples for the effectiveness of a new drug. The two samples can be dependent or independent, and you will explain the difference.

Concept being Studied

Your focus is on hypothesis tests and confidence intervals for two populations using two samples, some of which are independent and some of which are dependent. These concepts are an extension of hypothesis testing and confidence intervals which use statistics from one sample to make conclusions about population parameters.

What to Submit

Your research and analysis should be presented on the Word document provided. All calculations should be provided on a separate Excel workbook that should be submitted to your boss as well.

Rasmussen College Infectious Diseases Unit Statistical Analysis Report

Deliverable 7 – Statistical Analysis Report

Instructions

You are currently working at NCLEX Memorial Hospital in the Infectious Diseases Unit. Over the past few days, you have noticed an increase in patients admitted with a particular infectious disease. You believe that the ages of these patients play a critical role in the method used to treat the patients. You decide to speak to your manager, and together you work to use statistical analysis to look more closely at the ages of these patients.

You do some research and put together a spreadsheet of the data that contains the following information: Client number Infection disease status Age of the patient

You are to put together a PowerPoint presentation that explains the analysis of your findings which you will submit to your manager. The presentation should contain all components of your findings. For review, the components of the report should include: Brief overview of the scenario and variables in the data set Discussion, calculation, and interpretation of the mean, median, mode, range, standard deviation, and variance Discussion, construction, and interpretation of the 95% confidence interval Explanation of the full hypothesis test Conclusion

The calculations should be performed in your spreadsheet that you will also submit to your manager. You can find additional information on what to add to your PowerPoint presentation in this Word document. Use the questions in the worksheet as your guide for the contents of your presentation.

For your final deliverable, submit your PowerPoint presentation and the Excel workbook showing your work. Do NOT submit your Word document.

Regression Analysis Paper

This is a university senior level paper. The topic is about regression analysis and I put the project proposal below and you can see the guideline what would like to see on paper below too.

proposal

Regression analysis is used in various ways in various fields. In recent years, with the advent of smart devices, human beings have become able to accumulate and process more data, so regression analysis has become more popular. It is used in various names; data science, big data, artificial intelligence, machine learning and so on. We trust the conclusions obtained through this analysis and this conclusion serves as a compass for our decisions. However, this conclusion has limitations and I would like to discuss these limitations through this project.

what i would appreciate if i see these from the paper:

– the popularity of regression analysis from the real world. like big data, data mining…

– the strengths of this analysis, why it is popular now and why now compared to the past?

– the limitations of this analysis. for example, causation versus correlation, in-data versus outside of data…etc

– how to mitigate the limitations
