Question

Joseph Winne · Accepted Answer

Final Answer : C, Explanation :  The researcher's study is biased because the patients selected to participate in a fall reduction protocol are already at very low risk of falling.The researcher will not be able to determine if low fall rates after implementation of the protocol are due to the intervention or the low fall risk characteristic of the subjects.Placebo effect is not a factor in this research study.Fall risk studies are examples of quantitative research.The patients would not be harmed by a fall prevention protocol.
