Answer to Question 1

B
Feedback:
Statistical power refers to the capacity to detect true relationships. Statistical power can be achieved in various ways, the most straightforward of which is to use a large enough sample. With small samples, statistical power tends to be low, and the analyses may fail to show that the independent variable and the outcome are relatedeven when they are, thus reducing statistical conclusion validity. The other answers, although they may affect the study as a whole, do not reduce its statistical conclusion of validity.
