Question 1

What is a Type I & II Errors?

Accepted Answer

Type I error (α) is rejecting a true null hypothesis (false positive). Type II error (β) is failing to reject a false null hypothesis (false negative). Power = 1−β. Reducing α increases β.

Question 2

How does the Type I & II Errors work?

Accepted Answer

Type I rate = α (significance level, typically 0.05) Then: Type II rate = β (typically 0.20 for 80% power) Then: Larger sample size reduces both error types simultaneously.

Question 3

Can you give an example of how to use the Type I & II Errors?

Accepted Answer

Example: Input α=0.05 · β=0.20 gives a result of 5% false positive rate · 20% false negative rate · 80% power (Standard research settings).
