Research some data profiling tools that are well-suited for data quality assessment and provide appropriate sources for your findings. Based on your research, select at least one data profiling product of interest, describe its features in detail, and describe how it is used to analyze databases. Using your case study application, discuss how you would conduct a data quality assessment for it using the bottom-up and top-down approaches. 

Question: Is it better in terms of Type I and Type II error to delete tied values or to use the midrank correction?

Use at least three different sample sizes, two different significance levels, two values of “d”, two different distributions, and 10% versus 30% tied values.

Use any test in Chapters 2 – 7 of the text, except for Wilcoxon rank sum, Siegel-Tukey, and two-sample t-test.

Useful code:

In two diferernt paragraph give your personal opinion to  Alyssa Lucas and Felita Daniel-sacagiu 

 Alyssa Lucas 

As an RRT I have just recently was registered in the state of Indiana, which is a prerequisite to apply for any RT jobs in the state of Indiana. There are many available opportunities and certification in my career field that can help me expand my knowledge. Below is a list of specialty certification I can take through the National Board for Respiratory Care (NBRC) and work specifically in that specialty as an RRT.  

1. Certified Pulmonary Function Technologist
2. Registered Pulmonary Function Technologist
3. Adult Critical Care Specialist
4. Neonatal/Pediatric Specialist
5. Sleep Disorder Specialist

I would love to be specialized in all fields of my study eventually but my main goal I intend to begin at would be a registered pulmonary function technologist. This job would mostly be clinic hours working with a machine that measures breathing using different techniques. My next step is to eventually specialize in adult critical care or neonatal/pediatric care and work my way up in a large hospital in my area working for Riley’s Hospital for Children  or Indiana University Health Hospitals.

1. Volunteer opportunities:  BlueCross BlueShield of Tennessee

Each employee can sign up for volunteer opportunities and participate while on the clock. It gives employees the opportunity to give back.  Volunteering was put on hold due to Covid-19.  I have participated in many community volunteer opportunities and plan to continue when safe to do so.

1. CPHQ Certification: National Certification of Healthcare Quality https://nahq.org/certification/certified-professional-healthcare-quality/?keyword=cphq%20certification&matchtype=p&device=c&lpurl=https://cphq.nahq.org/xehhu&campaign=campaign&adgroup=adgroup&gclid=EAIaIQobChMIhcqYx–T7AIVDY-GCh33DgGlEAAYASAAEgJutfD_BwE.  Many healthcare companies are looking for professionals (for quality departments) that have a LEAN & Six Sigma or CPHQ certification.  People with this certification have demonstrated an extensive knowledge base of quality and quality measures.  I have received my green belt in Lean & Six Sigma.  I may attempt to obtain this certification.  It requires a lot of studying in preparation for the exam. 
2. Internship:  BlueCross BlueShield of Tennessee Career Development Program. 

http://webatwork.bcbst.com/wps/myportal/webatwork/content/news%20and%20events/news/news%20archives/2021%20career%20development%20programs%20seek%20participants/!ut/p/z1/t

It is a mentoring and job rotation program for BCBST employees.  It is designed to develop future leaders and introduce them to executive management and other divisions within the company.  Employees must apply and be nominated by the department director and are held once per/year.  I will likely apply for this program next year.  The application deadline has passed for this year. 

1. Pathways – Federal Internship Program: https://www.usajobs.gov/Help/working-in-government/unique-hiring-paths/students/.  This program is offered to students with recent graduates (within 2 years).  This is a Federal government internship with careers in the civil service area.  It will be difficult to participate in an internship program.  However, this program allows for part-time workers.  It requires 40 hours of formal training each year.  I plan to research this opportunity more.
2. Presidential Management Fellows Program:  https://www.opm.gov/policy-data-oversight/hiring-information/students-recent-graduates/#url=graduates. This program is open to recent graduates with advanced degrees.  There is a rigorous vetting process, but individuals may apply more than once.  This program was developed over 30 years ago and is designed to prepare participants for federal government leadership positions. This program seems incredibly involved.  I am happy with my current place of employment and it is unlikely that I will pursue this opportunity.

Standard performance measures are a way of collecting data across similar functions, processes, costs, and providers. Benchmarking against these standards has proven to be useful in healthcare as a tool to measure many facets of quality. Carefully evaluating these measures allows for management to design appropriate programs to assist with healthcare service needs and patients to make decisions about facility and provider services. Best Doctors, Inc. and WebMD are examples of these tools. Your discussions will focus on the use of information from these websites to make healthcare decisions.

Using the South University Online Library or the Internet, research about these measures and how they allow management to design appropriate programs to assist with healthcare service needs.

Based on your readings and research, answer the following:

Present a brief overview of the purpose for each of the Best Doctors, Inc. products. How are the “Best Doctors” of each type determined? Click here to visit the official Best Doctors website.

Next, click here to read a case study about Mary Jones.

Mary faced several challenges in her ordeal, mainly dealing with her diagnosis and treatment. This was a result of her ability to seek additional assistance and to find diagnosis. She reviewed the WebMD website for additional data and other specialty physician sources. Click here to visit the official WebMD website.
