Chamberlain College of Nursing Misleading Graphs Statistics Project
After exploring different types of graphs this week, it is unfortunate to learn that there are sometimes misleading graphs used in the news, politics, medicine, etc. in order to sway a decision or belief. Some items to watch out for in graphs are—Is there a title that explains what the graph is displaying?Are numbers on the axis spaced out proportionally or have they been varied to create a dramatic impression?Is the graph too loud? Does it have too many components that it distracts from content?Are there sources cited to know where the data came from?Use the internet to find a misleading graph.

Colorado State University Cars Critical Thinking Paper
Option #1: Critical Thinking: Cars
An expert who works for a car magazine obtained random data (rounded to the nearest thousand) among two categories of used or new cars: Domestic Foreign
The expert would like to understand sales based on list price (rounded to the nearest thousand dollars), sale price (rounded to the nearest thousand dollars), and number of days it takes to sell each car. The complete data set is in the file named Cars.
Managerial Report
Prepare a report (see below) that summarizes your assessment of the nature of the car market. Be sure to include the following seven items in your report.
Calculate descriptive statistics (mean, median, range, standard deviation, and coefficient of variation) to summarize each of the three variables for the all Domestic cars.
Use z-scores to determine if there any outliers in the data set for any of the three variables. If there are any outliers in any category, please list them and state for which category they are an outlier.
If a result is an outlier, state whether it is below or above the mean.
How can one use the above descriptive statistics to understand the Domestic car market better?
Could there be any other descriptive statistics that can help one understand the Domestic car market better?
Descriptive statistics (mean, median, range, standard deviation, and coefficient of variation) to summarize each of the three variables for the all Foreign cars.
Use z-scores to determine if there any outliers in the data set for any of the three variables.
If there are any outliers in any category, please list them and state for which category they are an outlier.
If a result is an outlier, state whether it is below or above the mean.
How can one use the above descriptive statistics to understand the Foreign car market better?
Could there be any other descriptive statistic that can help one understand the Foreign car market better?
Compare your summary results from #1 and #2. Discuss any specific statistical results that would help the car expert understand the two-car markets.
Develop a 98% confidence interval estimate of the population mean sales price and population mean number of days to sell for Domestic cars. What is the margin of error?
Interpret what each confidence intervals means. How can both confidence intervals provide useful car sales information?
What other confidence interval would you choose to compute to obtain more information related to Domestic car sales? Explain why.
What happens to the confidence interval as the level of confidence is increased?
Develop a 98% confidence interval estimate of the population mean sales price and population mean number of days to sell for Foreign cars. What is the margin of error?
Interpret what each confidence intervals means. How can both confidence intervals provide useful car sales information?
What other confidence interval would you choose to compute to obtain more information related to Domestic car sales? Explain why.
Assume the car expert requested estimates of the mean number of days to sell for the Domestic cars with a margin of error of seven days and the mean selling price of foreign cars with a margin of error of eight days.
Using 98% confidence, how large should the sample sizes be for each one?
How could the sample size formula be useful in understanding both types of car businesses? What are some advantages of a larger sample size?
Suppose a Domestic car has a list price of $30,000 and a Foreign car has a list price of $30,000. What is your estimate of the final selling price (based on the percent difference for the sale and list price) and number of days required to sell each of these cars?
How would these two estimates be useful in this application?

Harvard University Wk 7 Find the Risk of Infection for Each Patient Excel Task
Part 2 peer video:
https://www.youtube.com/watch?v=y6ZlpCAPQpg&feature=youtu.be
This exercise allows you to examine how the quality of hospital care is evaluated through data obtained from electronic health records. This exercise is discussed in several health administration courses, including courses on quality improvement, informatics, or statistics. In practice, the need to analyze these types of data arises in improvement teams, where managers, clinicians and sometimes patients work together to systematically improve healthcare processes.
You can find the solution here and here.
Part 1: In this assignment, you are asked to examine if prophylactic antibiotics are discontinued within 24 hours after the end of surgery. Instead of providing you with the data, we ask that you download the data on the web so that you learn more about the source of the data and the peculiar organization of the data. Hospital Compare provides information on many quality indicators. In this assignment, you are asked to focus on the failure to stop the use of antibiotics post-surgery. The Hospital Compare web site provides the following rationale for why this measure of quality is helpful: "A goal of prophylaxis with antibiotics is to provide benefit to the patient with as little risk as possible. It is important to maintain therapeutic serum and tissue levels throughout the operation. Intra-operative re-dosing may be needed for long operations. However, the administration of antibiotics for more than a few hours after the incision is closed offers no additional benefit to the surgical patient. Prolonged administration does increase the risk of clostridium difficile infection and the development of antimicrobial-resistant pathogens." To complete this assignment complete the following tasks:
a.Download Hospital Compare data for the years starting from 2015 till now.Merge the file "HQI_HOSP_TimelyEffectiveCare" across all databases for different years.
b.Select measure ID "SCIP_INF_3"; this measure refers to prophylactic antibiotic use. Select to work with data from "Southeast Alabama Medical Center"; this is provider ID "010001".
c.Calculatethe rate of overuse of antibiotics.In these data, the field "Score" refers to the number of patients with overuse of antibiotics.The field "Sample" refers to all selected surgical patients with no evidence of prior infection. The ratio of Score to Sample provides the rate of overuse of antibiotics.
d.Construct a control chart showing the rate of overuse of prophylactic antibiotics over time in Southeast Alabama Medical Center.Download the needed data using the following databases (if new data is available, please use them)
You can find the solution here Click for more options.
The student peer video shows that data across the years us merged using SQL. You can do the same merger without using SQL. Open the CSV files (you can ignore access files for old years.) Filter the data by the measure you are interested in Copy the sheet with the relevant filtered data from each CSV file into a single sheet within the new Excel file. In a sheet titles "ALL" inside the Excel file, use cell reference to bring the data in different sheets to the "ALL" sheet. Do your analysis on this sheet.

Part 4: Download Hospital Compare data.In these files, the denominator indicates the number of patients.Whether the hospital had above average payments are reported in different fields: [Compared to National], [Category], and [Payment Category]
Select data that meet the following conditions:
a.Select the "PAYM_30_AMI" measure
b.Select hospitals that in the denominator do not have "Not Available".
Construct a control chart showing the probability of change over time.
To assist, we have downloaded some of the necessary files.You can add to these additional more recent files from the Hospital Compare site.Since the data on AMI payments does not change in the files, you can save time and read only the following files into a new database:

Some of you do not have Microsoft Access. Early files in Hospital Compare used Microsoft Access and later files used CSV (a file format that opens with Excel.) To remedy this situation, I am replacing Microsoft Access files with Excel Files. If you have to look at only AMI quality measures you need to use the filter feature within Excel.
Use these files:
