Example Question #1 : Statistics
Type II errors occur when a researcher incorrectly __________ the ___________ hypothesis; therefore, they erroneously reject the __________ hypothesis.
Possible Answers:
accepts. . . null. . . alternative
rejects. . . alternative. . . null
rejects. . . null. . . alternative
accepts. . . alternative. . . null
None of these
Correct answer:
accepts. . . null. . . alternative
Explanation:
Type II errors occur when we fail to reject a false null hypothesis. As a result, the researcher will incorrectly accept the null hypothesis and erroneously reject the alternative hypothesis. This commonly occurs when sample sizes are small. Larger sample sizes ensure that statistical measures will identify a practical difference when one truly exists.
