Which statement correctly expresses a conclusion of a hypothetical research study?
 
  1. A significant difference exists between the numbers of associate degree nursing graduates and baccalaureate degree nursing graduates who fail the licensing exam on the first attempt.
  2. Associate degree nursing graduates appear to be more likely than baccalaureate degree nursing graduates to pass the licensing exam on the first attempt.
  3. Associate degree nursing graduates were more likely than baccalaureate degree nursing graduates to pass the licensing exam on the first attemp .
  4. There were no differences between associate degree nursing graduates and baccalaureate degree nursing graduates in performance on the licensing exam.

Question 2

Which statement accurately demonstrates that a research finding is statistically and clinically significant?
 
  1. The intervention demonstrated decreased heart rate of the adults (81.76 to 77.76, p = 0.18).
  2. The intervention demonstrated decreased P pain intensity (4.65 to 2.35, p = 0.001) on the second hospital day.
  3. The intervention demonstrated decreased respiratory rate of the adult sample (18 to 14, p = 0.004).
  4. The intervention demonstrated decreased complication rate at 6 weeks after hospital discharge (6 to 18, p = 0.27).

Answer to Question 1

2
Rationale 1: This statement describes a directional hypothesis.
Rationale 2: This conclusion is tentative (appear). We can never prove our findings.
Rationale 3: This statement describes a finding.
Rationale 4: This statement describes a finding.
Global Rationale:

Answer to Question 2

2
Rationale 1: Although this change was statistically significant, both values fall within the normal range of heart rate, and there would be no clinical need for the intervention to be used.
Rationale 2: The statistical significance of this statement suggests that the demonstrated difference would occur by chance once in one thousand times. It is also clinically significant because pain intensity is a perception, which may be useful in a clinical setting.
Rationale 3: Although this change was statistically significant, both values fall within the normal range, and there would be no clinical need for the intervention to be used.
Rationale 4: This statement demonstrates an increase as opposed to a decrease. If a result is in the opposite direction from the prediction of the researcher, the intervention studied would not be useful clinically. Further, the difference would occur by chance once in 47 times, which suggests that chance alone could explain the difference.
Global Rationale:
