A nurse educator is interested in the difference between traditional clinical instruction in pediatrics and simulated pediatrics instruction in a BSN (Bachelor’s of Science in Nursing) program. She randomizes students to receiving 50 hours of either traditional clinical rotations in a pediatrics department or 50 hours of simulated instruction in pediatrics. At the end of the 50 hours, the students are assessed for clinical competency in pediatrics using a standardized instrument that yields a pass/fail result. Her research question is: Is there a difference in between the traditional clinical group and the simulation group on rates of passing the competency assessment? What is the appropriate statistic to address the research question?
Appropriate statistic to address the research question:
Chi square test of association between two categorical variables:
EXPLANATION:
Here, the 2 categorical variables are:
Variable1 : Traditional clinical rotations in pediatrics department
and
Variable 2: Simulated instruction in pediatrics
