Quizplus · Accepted Answer

The scientific community is likely to have concerns over the interpretation of the p-values primarily because the researcher was not transparent with the number and type of analyses he conducted. Without a clear understanding of the number and type of analyses conducted, it is difficult to determine if the p-values reported are valid or if they are simply the result of multiple comparisons. This lack of transparency can lead to questions about the validity of the researcher's findings.
