Transform Data: Dataset And Variables

Other (Not Listed) Instructions:

Part 1: Transformations

Use the consumer patient survey dataset for this assignment. Name the dataset Survey.  To view the consumer patient survey dataset, Go to the Books and Resources for this Week module and click on the U.S. 

  1. Change the class of the "HCAHPS Answer Percent" variable to a number using the command survey$`HCAHPS Answer Percent`<-as.numeric(survey$`HCAHPS Answer Percent`).
  2. Apply three transformations to the data. (Hint: use summary and hist or boxplot commands, then the transformation of the variable; consider skew and kurtosis).
  3. Visually and numerically determine the shape of all of the distributions for this variable.

Part 2: Missing Data

  1. Create a subset of data from Rhode Island (RI) using the subset command sub<-subset(survey,State=="RI").
  2. Determine the number of NA values in this subset for the HCAHPS Answer Percent variable.
  3. Replace NA with 0 using the which(is.NA(<variable>) <- 0 command.
  4. Replace NA with the mean use <- mean(<variable>,na.rm = TRUE).
  5. Visually and numerically determine the shape of all of the distributions for this variable.

Then address the following in a research paper with an introduction, method, and results section:

  1. Identify the dataset and variables and provide context to the research used to collect the data (in an introduction section).
  2. Identify the analysis performed, pros and cons of calculation, and why they are used (in a method section).
  3. Describe and interpret results (in a results section).
  4. Include references.
  5. Include all R code as an appendix.

Length: 5-7 pages

References: Include a minimum of 3 scholarly resources

Transform Data Student’s Name Institutional Affiliation Transform Data Identify the dataset and variables and provide context to the research used to collect the data (in an introduction section). In recent years, there have been attempts to elevate the quality of healthcare services provided by hospitals. Consequently, in May 2005, the US Department of Health via the National Quality Forum (NQF) embarked on a survey to gather information on patients’ satisfaction for the experience they had in various hospitals. The forum represents a consensus of several health care providers, consumers (in this case patients), professional associations, buyers, federal agencies, and certified research and quality organizations. Patients in the in-patient unit were the primary target of this data collection methodology. To avoid bias, patients wrote down their perspectives of care provided by the hospitals they had visited. Information collected was then compiled and sorted out to come up with a public report of the whole survey. Comparisons were made across all hospitals and meaningful conclusions drawn as per the responses of the public or rather patients. For standardization, a uniform measurement approach was incorporated for fairness. The spade to spade approach gave birth to HCAHPS Survey i.e. Hospital Consumer Assessment of Healthcare Providers and Systems Survey. Basically, the HCAHPS Survey can be defined as a compiled set of questions with a wider personalized set of hospital-specific items that are a supplement to data collection. As a compliment, these items aid in improving internal customer services and the overall quality of the hospital related stuff. The main objective of the HCAHPS Survey is to come up with measurable comparisons among these healthcare facilities that can be used to: * Improve the quality of health care * Help consumers make a choice on which facility to visit based on the rating * Enhance public accountability via transparency of hospital’s quality To ascertain the public of its authenticity, the survey ensures that it remains credible, useful and above all realistic. All information in this survey is accessible to the public for its convenience. A detailed approach of the survey includes twenty-one patient perceptions on health care and rating items that consolidate to a nine key topic approach (Drukker, 2011). The topics include communication with doctors, with nurses and about medicines, the responsiveness of entire hospital staff, pain management techniques, overall cleanliness of the hospital and its immediate environs, in/out-patient discharge information, discreetness of the hospital surroundings and care transitions. Four screener queries and seven population-related items focus on tuning a patient’s mix in the hospital beside the analytical purpose. The governance modes approved in the survey are mail, telephone, and active interactive voice responses. Entirely, the survey has a total length of 32 questions. In this paper, the dataset on scrutiny is one from the HCAHPS Survey. The variables in the dataset include; * Hospital’s provider ID * Name of the facility * Address * City * State * ZIP code * County name * Phone number * HCAHPS measure ID * HCAHPS question ...
