Probability of type 2 error symbol
The probability of making a Type I error is the significance level, or alpha (α), while the probability of making a Type II error is beta (β). These risks can be minimized through careful planning in your study design. Example: Type I vs Type II error You decide to get tested for COVID-19 based on mild symptoms.
