1. The quality improvement team is reviewing
Time-series
quarterly incident reports and evaluating the
effect of Six Sigma strategies on the quantity
of medication errors over the past two years.
The team hypothesizes a contin- uous
reduction in medical errors for each
quarter.The sample consists of patient
clinical and demograph-
ic characteristics. Unfortunately, causation
cannot be determined from the data available.

the team's hypothesis? Time-Series
Cross-
Sectional
Pretest-
posttest
Randomized Control Trial
