Explain Why a Researcher May Need to Adjust His or Her

Question

Examlex · Accepted Answer

The Answer is A researcher may need to adjust his or her alpha level using a Dunn-Sidak test in order to control for the increased likelihood of making a Type I error when conducting multiple comparisons. When conducting multiple statistical tests, the probability of making at least one Type I error (rejecting a true null hypothesis) increases with each test conducted. The Dunn-Sidak test is a method for adjusting the alpha level to account for this increased risk of Type I errors. By using a lower alpha level, the researcher can reduce the overall probability of making a Type I error across all comparisons. This helps to ensure that any significant findings are not simply due to chance and increases the reliability of the research results. Adjusting the alpha level using a Dunn-Sidak test is therefore an important step in maintaining the validity of statistical analyses when conducting multiple comparisons.
