Which of these strategies is most commonly used to reduce the probability of type II error?
A) use a non-directional (two-tailed) instead of a directional (one-tailed) alternative hypothesis
B) never conclude an effect exists regardless of the evidence
C) increase sample size
D) lower alpha

Question

Quizplus · Accepted Answer

Increasing the sample size can decrease the probability of type II error by providing more data and reducing the likelihood of chance variability. Other strategies such as using a non-directional alternative hypothesis or lowering alpha may reduce the probability of type I error but do not directly address type II error. The strategy of never concluding an effect exists regardless of the evidence is not a valid statistical strategy.
