demographic characteristics. Unfortunately, causation cannot
be determined from the data available. Which research method
should be used to test the team's hypothesis? Time-Series
Cross-Sectional

variables. The analyst hypothesizes that hospital efficiency
should have increased each year after the PPS was
implemented. Which research method should the analyst use?

scenario? To confirm overall diagnoses across time To identify
the average patient satisfaction score To create a baseline in
the organization's current performance To run a regression to
ensure patients are eligible for bonus programs - ANSWER-To
identify the average patient satisfaction score
