Suppose the results indicate that the null hypothesis should not be rejected; thus, it is possible that a type II error has been committed.Given the type of error made in this situation, what could researchers do to reduce the risk of this error? Increase the sample size. Choose a 0.01 significance level instead of a 0.05 significance level.
Question
Suppose the results indicate that the null hypothesis should not be rejected; thus, it is possible that a type II error has been committed.Given the type of error made in this situation, what could researchers do to reduce the risk of this error? Increase the sample size. Choose a 0.01 significance level instead of a 0.05 significance level.
Solution
In order to reduce the risk of committing a Type II error, researchers could indeed increase the sample size. A larger sample size can provide a more accurate representation of the population, which can help to detect a true effect if one exists.
Additionally, choosing a lower significance level (like 0.01 instead of 0.05) can also help to reduce the risk of a Type II error. A lower significance level means that the threshold for rejecting the null hypothesis is more stringent, which can help to avoid false negatives. However, it's important to note that this could increase the risk of a Type I error (rejecting a true null hypothesis).
Therefore, researchers need to balance these considerations based on the specific context and objectives of their study.

A researcher wants to avoid making a type II error. Which of the following actions would be the most effective in reducing the risk of a type II error? Increase the sample size. Choose an alpha level of 0.01. Choose an alpha level of 0.05.
Suppose that at the end of the five-year study described above, a greater proportion of the hormone-treated group have breast cancer and heart disease. This observed difference is statistically significant. Researchers are so alarmed by the results that the experiment is ended early to prevent further harm to the health of the women participating in the hormone group. Since the null hypothesis was rejected, it is possible researchers made a type I error.Given the type of error made in this situation, what could researchers do to reduce the risk of this error?
