The Tukey test limits familywise error by ______.
A) changing the degrees of freedom
B) placing limits on the number of groups that can be in a research study
C) changing alpha from .05 to .10 for each analytical comparison
D) increasing the critical value of the statistic needed to reject the null hypothesis for each comparison
Familywise Error
The chance of encountering one or more incorrect rejections, known as type I errors, while testing several hypotheses.
Critical Value
A critical value is a point on the scale of a statistical distribution that corresponds to a specified level of significance for the testing of a hypothesis.
- Pinpoint the appropriate statistical approaches for minimizing familywise error in multiple research configurations.
- Realize the essentiality of controlling type I errors within hypothesis examination procedures.

Final Answer :
D
Explanation :
The Tukey test controls the familywise error rate by increasing the critical value of the statistic needed to reject the null hypothesis for each comparison. This means that the chance of making a Type I error (rejecting the null hypothesis when it is actually true) for any of the pairwise comparisons is reduced, thereby limiting the familywise error rate.
Learning Objectives
- Pinpoint the appropriate statistical approaches for minimizing familywise error in multiple research configurations.
- Realize the essentiality of controlling type I errors within hypothesis examination procedures.
