2. Explicate the covariance between two numeric (ratio or interval) variables and its significance and define correlation between these two variables, and its significance, and provide a hypothetical example of evaluating covariance and correlation along with interpretations. State and explain if the correlation between two variables and simple regression are of the same nature. Describe the rank correlation, its purpose, and significance. Discuss why the rank correlation is bound between -1 and 1.

Activity 9 – CLO 1, CLO 2, CLO 3, CLO 9, CLO 11, CLO 12

Populations A and B are both measured in the same ordinal scale. A sample from these populations is taken which contains two (2) elements from A and three (3) elements from B. State all possible rank ordering of the elements in the sample. Under validity of the null hypothesis that the medians of the two populations are identical, assign probabilities for all possible values for the statistic in the MWW test on equality of the medians. For each value of the test statistic, state if the null hypothesis is rejected, and also evaluate the associated p value. Use 0.05 once and then 0.1 for significance level.

For your Final Project Article Review, you will review and analyze published research that you might encounter as a health professional. You will select two journal articles from the provided list on a topic of interest. You will create an article review that identifies the articles and their relevance to your field; summarizes the articles, including their findings; compares and contrasts the statistical methods used in the articles; explains why the methods used were appropriate; discusses their limitations; and concludes with recommendations for future work.  Statistics homework help

Final Project Article Review is divided into three journals, which will be submitted at various points throughout the course to scaffold learning and ensure quality final submissions. These article journals will be submitted in Modules Two, Five, and Six. The completed article review will be submitted in Module Eight.

Imagine you are a biostatistician working at a local health organization. Part of your job is to analyze trends and draw conclusions about health issues that affect your organization. Your supervisor has asked you to do a quick literature search for published research on an upcoming topic as preparation for a new project. The goal is to understand the current biostatistical methods and guidelines being used on similar studies so that you could eventually use that to inform the design of the new study. Your job is to find a minimum of two research articles on your topic from the Final Project Article Review Articles List document, examine the broad health question(s) addressed in each, and critically assess the statistical methods used to analyze the data and arrive at the articles’ conclusions. You will present the results of this analysis to your supervisor and peers in an article review. Specifically, your article review must address the following critical elements:

Attached was the midterm project now i need the final project done

Requirements:

No more than 2 to 3 pages
Present the findings using the skillset acquired (topics covered) in class.
Also include the dataset with the analysis (could be excel or any statistical package). You should provide details of the analysis in an Appendix.
How are the 40 points given: 10 for each Module you choose to apply. (For example, you choose regression to test an association or predict an outcome, you get 10 points for that analysis)

Data Analytics is a subject that can be best appreciated only when applied to a dataset you are familiar with. The aim of this project is to achieve that. Do not view this project as a hurdle in the course, rather a bridge to connect the topics you learnt to your work or subject domain. There are five main modules in this course: Statistics homework help.

Module 1 : Normal Distribution (Percentile, distribution of means, and chance of occurrence if we assume normal distribution)
Module 2 : Confidence Interval Estimation (Including Sample Size determination)
Module 3 : Inferences from data (Hypothesis testing, i.e., confirming or checking if a claim made about the data. In this module, we dealt with only one sample)
Module 4 : More Inferences from data (Multiple samples)
Module 5 : Regression analysis (Both simple and multiple, apart from basic ANOVA)
Bring your own data from work (you can remove any private or confidential information, for example: if you are bringing any sales or cost data of an item/product or service – the name can be masked)
Use data from your previous work or company you have access to (again you can remove any private/confidential information)
Use data from public domain – In today’s world, there is no dearth of structured data. Here are some places where you can get data from:
Any data source you have access to like the Hawkes Learning Resources
Datasets (1) (Links to an external site.) from Hawkes
Datasets (2) (Links to an external site.) from Hawkes – Look at the additional datasets, not the chapter datasets
U.S. Bureau of Labor Statics (Links to an external site.)
U.S. Government’s open data (Links to an external site.)
Center for Medicare and Medicaid services (Links to an external site.) Statistics homework help.
Kaggle datasets (Links to an external site.)
WHO Data repository (Links to an external site.)
World Bank Data (Links to an external site.)
Google Public data explorer (Links to an external site.)
Amazing visualization or graphics
But remember, we need the data to do analysis, if you look at the bottom of any figure – Google would provide the source name, and you can retrieve data from there.
Any sports data (from the appropriate website, getting data in structured format for several years might be challenge, but a few minutes or an hour – you can do it)
For example – Cricket data could be obtained from espncricinfo (Links to an external site.). Statistics homework help.
