3.8.B—Calculate the probability of Type I and Type II errors

Calculate the probability of Type I and Type II errors.

• The probability of making a Type I error is defined as the significance level, α. For a given study and hypothesis test, the probability of making a Type I error is typically set to a small value (e.g., 0.01, 0.05, 0.10) prior to collecting the data.
• The probability of making a Type II error is 1 power.
