What does P < .05 mean?
The result is not significant for most nursing research, which requires more rigor.
There is a 1-in-5 chance of the result occurring again by chance alone.
The researcher is 95% confident that the result did not happen randomly.
Only 5 out of 100 nursing research studies would report this result as significant.
The Correct Answer is C
A. This statement is incorrect because a p-value less than .05 typically indicates statistical significance in nursing research.
B. This statement is incorrect because it misinterprets the meaning of p < .05. It does not mean that there is a 1-in-5 chance of the result occurring by chance alone.
C. A p-value less than .05 indicates that there is less than a 5% chance that the observed result occurred due to random chance. Therefore, the researcher can be 95% confident that the result did not happen randomly.
D. This statement is incorrect because it misinterprets the meaning of p < .05. It does not mean that only 5 out of 100 nursing research studies would report this result as significant.
