How do you know if you made a type 1 error
WebThe risk of making a Type I error is the significance level (or alpha) that you choose. That’s a value that you set at the beginning of your study to assess the statistical probability of obtaining your results ( p value ). The significance level is usually set at 0.05 or 5%. WebStep 1: Express the significance level as a decimal between 0 and 1. Step 2: State what a type 1 error is in the context of the example. Step 3: State that the probability that a type 1 …

A Type I error means rejecting the null hypothesis when it’s actually true. It means concluding that results are statistically significant when, in reality, they came about purely by chance or because of unrelated factors.
