As the effect of the independent variable increases, the likelihood of observing a significant difference between the groups (i.e. rejecting H ₀) also increases. This leads to an increase in power, which is the probability of correctly rejecting a false null hypothesis. The probability of making a Type II error (i.e. failing to reject a false null hypothesis) decreases as power increases. Therefore, the correct answer is B.

With Alpha and N Held Constant, as the Effect of the Independent
