baseline measurement to include patients in a research project.

second group will work with physical therapists on a regular
exercise program; the third group will follow the diet and engage in
the exercise.

A hospital CFO is analyzing the cost benefits of using the patient
reminder system, which was implemented over a year ago, to see if
the automated system results in less missed appointments ("no-
shows").
She is comparing quarterly reports from this past year on volume of
patients who did not show up to their appointments, to the volume
of patients of the previous year, who did not show up to their
appointments, to see if the automated system has proven effective.
She is considering other variables as she reviews the data, but is
primarily analyzing the number of "no-show" patients from last

There are two standard treatments for children with ADHD who
display a specific set of characteristics. One treatment is a cognitive
behavioral intervention, and the other is a dietary and biomedical
intervention. Both treatments have equally strong clinical evidence
supporting their efficacy. A researcher proposes a comparison of
the two interventions to determine which is preferable. The
children will be randomized to one of two groups: half of the
children will receive the cognitive behavioral intervention and the
other half of the children will receive the dietary and biomedical
intervention. Which test is appropriate to determining the
preferable treatment? -
correct answer ✅Cross-sectional
The vice president, CMO, and Operations Team collected data on
resources used by patients who have undergone coronary bypass
and the length of stays for a defined population of patients who
received CABG surgery. Since the raw data is complex to discuss and
evaluate, the team will use descriptive statistics to analyze the data
to support their decisions for recommendations.
