Multiply the chosen significance level (α) by 100 to determine the probability of a Type I error as a percentage.
The Type I Error Calculator is a valuable tool in hypothesis testing, helping to quantify the probability of rejecting a true null hypothesis. Often referred to as a “false positive,” a Type I error occurs when evidence is mistakenly deemed statistically significant.
This calculation aids researchers in maintaining precision and reliability in their studies.
