Which of these strategies is MOST commonly used to decrease type II error? A) using a non-directional (two-tailed) alternative hypothesis (H₁) B) using a directional (one-tailed) null hypothesis (H₀) C) increasing sample size D) lowering alpha

Question

Quizplus · Accepted Answer

Increasing sample size allows for a greater likelihood of detecting a true difference between the groups being compared, thus reducing type II error. Choices A and B affect the level of alpha, which does not directly impact type II error. Lowering alpha (Choice D) decreases the probability of making a type I error, but does not directly impact type II error.
