◍ Question # 29: The following weights were recorded for children in a
pediatrician's office: 93, 84, 70, 48, 59, 66, 88, 94, 84, 67, 74, 58, 82. The
analyst wants to see the distribution of the weights, but still be able to see
the individual values. Which method of display should be used?
A. Box plot
, B. Stem plot
C. Bar chart
D. Pie chart.
Answer: B. Stem plot
◍ Data warehouses.
Answer: These assimilate data from multiple transaction systems. Data
warehouses can be used to distinguish larger trends in data from multiple
sources
◍ HRRP.
Answer: Affordable Care Act (ACA) added a section to Social Security Act
in 2012, requiring CMS to reduce payments to hospitals with excessive
readmissions. Data gathered is response to the Hospital Readmissions
Reduction Program (HRRP), which is a Medicare value-based purchasing
program.

D. Quantitative to quantitative.
Answer: D. Quantitative to quantitative
◍ Evidence-based practice.
Answer: Healthcare administrators must have a working knowledge of
statistics in order to make sound, effective decisions when using research to
inform treatment and processes. Studies show that using analytical skills to
make decisions based on quality data will result in increased patient
satisfaction and improved outcomes (Scott & Mazhindu, 2014). In order to
discern the highest-quality research, administrators must have the expertise
necessary to objectively analyze statistics for validity. For both
professionals and patients, a basic understanding of research and statistics in
