Descriptive Data Analysis and Measure of Central Tendency & Dispersion Paper
You will undertake an analysis
based on a self-designed fictitious study that utilizes statistical
methodologies. You will first develop a fictitious problem to examine -
it can be anything. For example, maybe you want to look at whether
scores on a standardized college placement test (like the SAT) are
related to the level of income a person makes 10 years after college;
Or, whether those who participate in a Leadership Training program rated
as better managers compared to those who do not; Or, whether ones
political affiliation is related to gender. These are just a few
examples; be creative and think about what piques your interest. You
might also address a problem that you may want to look at in future
research for a dissertation or post-graduation research you may want to
do. You will use either EXCEL or SPSS to conduct the analysis. Your
analysis report should include the following components:Describe your research study.State a hypothesis.List
and explain the variables you would collect in this study. There must
be a minimum of three variables and two must meet the assumptions for a
correlational analysis.Create a fictitious data set that you will analyze. The data should have a minimum of 30 cases, but not more than 50 cases.Conduct a descriptive data analysis that includes the following:
a measure of central tendencya measure of dispersion at least one graphBriefly interpret the descriptive data analysis.Conduct
the appropriate statistical test that will answer your hypothesis. It
must be a statistical test covered in this course such as regression
analysis, single t-test, independent t-test, cross-tabulations,
Chi-square, or One-Way ANOVA. Explain your justification for using the
test based on the type of data and the level of measurement that the
data lends to for the statistical analysis.Report and
interpret your findings. Use APA style and include a statement about
whether you reject or fail to reject the null hypothesis. Here are some
resources that will help you with APA formatting in this step:Reporting Statistics in APA StyleReporting Results of Common Statistical Tests in APA FormatCopy and paste your Excel or SPSS data output and place it in an appendix.Submit
an annotated bibliography of five articles directly related to your
dissertation topic. For each article, please provide the reference in
APA format and then answer the following questions:1a. If a
study: What was the purpose of this study? Briefly summarize how they
designed the study and collected their data. What, for you, was the most
salient result they found?1b. If not a study: What was the purpose of the article and what for you was the key take-away message?2.
What are the main strengths, weaknesses, and unique aspects of this
resource?3. How might you use this resource in the future (e.g., I might
use this article in my literature review to support the need for my
study; I might use the measure they developed in this study; I might use
the same theory used in this study....)

MHA-FP5017 Assignment 4- Presenting Statistical Results for Decision Making
Vila Health ® ActivityPresenting Statistical Results for Decision MakingIntroductionYour OfficeStakeholder InterviewsEmail ResponseConclusionIntroductionAt any enterprise, statistical results can point the way to better decisions. This is especially true in health care, where trends or changes in patient care or results can have powerful effects on health care organizations — clinical effects, and financial effects. Knowing the facts about trends and changes is crucial to navigating them, which means that in many ways, statistical results are powerful tools.But they’re less powerful if nobody understands them. More often than not, stakeholders in health care organizations are not well versed in statistics or data analysis. Especially for these stakeholders, it’s critical to make careful choices about which numbers to include — and how to talk about those numbers. Doing so helps you to present statistical results in a way that’s understandable and actionable even for those with less data literacy.In this activity, you’ll have an opportunity to analyze a health trend at a large urban hospital, and to decide which results of the analysis are most important to communicate to the stakeholders concerned with it.Your OfficeYou are an analyst in the Quality Assurance department at St. Anthony Medical Center, a large hospital in Minneapolis, Minnesota. You have an email from David Brooks, the manager of Quality Assurance, in which he explains your next assignment.EmailFrom: David BrooksSubject: HACsHello! So I’m aware that you’re relatively new around here, but I’ve got to pull you in on an important project. Here’s the short version, and I can answer questions later if this isn’t enough background.Since you’re in health care, you must know that hospital-acquired conditions (HACs) are a big deal. Hospitals are designed from the ground up to minimize them, but the fact is that hospitals always have a lot of bugs floating around and that means they’re a constant danger. And while we try to minimize mistakes, health care professionals are human, and sometimes mistakes cause real problems.The hospital’s board is getting worked up about them again, because we’ve had some high-profile cases where a patient went home and had to be readmitted because of a mistake or an infection they picked up while they were here. They’re worried about PR, of course, but they’re worried about patient outcomes, and — of course — financial reimbursement and penalties, too.What I need you to do is start working on a presentation about HACs here, specifically as they relate to staffing levels and skill mix. That presentation should explain our recommendations to the board. You’ll want to include some statistics to bolster our case, so take a look at the AHRQ National Scorecard on Hospital-Acquired Conditions and the CMS Hospital-Acquired Conditions Reduction Program. Look at published research about the relationship between HACs and staffing levels, too.Let’s get this right; this is our chance to get the board to understand that HACs will go down if they do what we recommend.Go talk to Rick Susskind first; he’s our senior data analyst and he’s already been working on this. He has completed a data analysis on this, and he can explain what the variables are. You’ll have to talk to a few other people too, to get everything you need.DavidEmailFrom: Rick SuskindSubject: HAC DataHi! I got your message about the HAC question. I’ve attached a spreadsheet of the data analysis we’ve got on that.Here are a few variables that might be unclear:HAC_Rate: That’s the number of HACs per 1,000 discharges. You could say it’s the measure for the extent of hospital errors.Nursing_HPPD: That’s the number of nursing staff hours per patient day. It’s the hospital’s nurse staffing level.Skill_Mix: That’s obviously about skill mix, but specifically, it’s the percentage of nursing staff hours that are provided by registered nurses, as opposed to other professionals.ALOS: That stands for average length of stay; it’s the number of inpatient days per hospital discharge. It’s a measure of how efficient the hospital is.Let me know if you have other questions! Oh, you’ll need to find out how many discharges we have per year. I don’t know that, but Troy Holland, our vice president of patient services, will know.Attachment: HAC AnalysisStakeholder InterviewsTroy HollandVice President of Patient ServicesIt’s nice to meet you! Yep, I’ve got those discharge stats. I’m assuming you’re confining your analysis to the last full year? If so, the number of discharges for last year was 10,000. That includes both adult and pediatric discharges.What I don’t have is information about nurse staffing or costs. For those, you’ll want to talk to Jackie, the chief nursing officer.Jackie SandovalChief Nursing OfficerHello. I understand you need some data about our staff costs related to nursing. I’ve got three numbers for you.Our cost per nurse is $72,000. Now, that’s an average of nurses and registered nurses.Our cost per registered nurse is $85,000.Per licensed practical nurse, it’s $52,000. Those numbers include salary, benefits, and overhead.You had asked about some other costs, but I don’t have those. You’ll want to talk to the CFO, Owen Welch.Owen WelchChief Financial OfficerHey, I’ve only got a couple of minutes but here’s what you asked about: Our cost per inpatient day is $2,600, and the penalty per HAC is $5,700.Email ResponseIt looks like David has followed up with you about the data analysis project you’re working on. Review David's latest message to you and send a reply with your initial thoughts.EmailFrom: David BrooksSubject: HACsThanks for doing all that running around. Now that you’ve got the data analysis you need, I’d like you to do some thinking about what results you’re going to include in the presentation. Remember, it’s the board, not a bunch of number geeks. You’ll want to give them the statistical results they need to make a decision, not just every bit of data we have.Write down a list of numbers you’re thinking about including in your presentation. We really need to make a data-driven recommendation to the board, and I’d really appreciate your expertise. Thanks!ReplySubject: RE: HACsThis message has not been composed yet.ConclusionIn this activity, you saw that while complicated analysis of data is an important step in guiding decisions at health care organizations, it’s not the only step. Decision makers need to understand how the data were collected, how variables are measured, and whether the analysis tools and techniques were appropriate.You also gathered necessary data for an analysis of HACs, nurse staffing levels, and skill mix, and did some pre-work on a presentation of the data analysis to the hospital’s board.

World population statistics
InstructionsToday there are 195 sovereign countries in the world that are officially recognized. One can choose to look at many types of data coming from these countries, as there is a plethora of existing information. For this assignment you will be looking at populations of cities within Poland at five different times (depending on when a census was taken). The data for these cities can be found in the file named Populations. Use all of the data points for each of the years given, but please note that not every city has a population for each census.Prepare a report (see below) using the numerical methods of descriptive statistics presented in this module to show how the populations of the cities vary over the years (growth rates). Be sure to include the following three (3) items in your report.Compute descriptive statistics for each of the years along with an explanation of what the descriptive statistics tell us about the different years. Are they continually growing, or is there a decrease in the number of people? The descriptive statistics will include the mean, mode, range, standard deviation, and the 5-number summary (minimum, first quartile (Q1), median (Q2), third quartile (Q3), and maximum).Determine which cities, if any, should be considered outliers in each of the years? If there are any outliers in any year, please list them and state for which year each one is an outlier. Use the z-score method to determine outliers for this question showing the z-score calculations for each city and year in your spreadsheet.Determine the correlation coefficient between the first year and each of the other years. Please provide an explanation of the relationships. Show your calculations for each correlation coefficient within the spreadsheet.Paper RequirementsWrite a report that uses the Written Assignment Requirements under the heading Expectations for CSU-Global Written Assignments found in the CSU-Global Guide to Writing and APA. Items that should be included, at a minimum, are a title page, an introduction, a body which answers the questions posed in the problem, and a conclusion paragraph that addresses your findings and what you have determined from the data and your analysis. As with all written assignments, you should have in-text citations and a reference page. Please include any tables of calculations, calculated values, and graphs associated with this problem in the body of your assignment response.Note: You must submit your Excel file with your report. This will aid in grading with partial credit if errors are found in the report.
