How does the choice of significance level affect the probability of making a Type I error?

  • Higher significance level leads to higher probability of Type I error
  • Lower significance level leads to higher probability of Type I error
  • Significance level has no effect on the probability of Type I error
  • The choice of significance level affects the probability of Type II error, not Type I
The significance level (alpha) is the probability of making a Type I error. So, a higher significance level increases the chance of rejecting the null hypothesis when it's true, hence increasing the probability of a Type I error.
