Reality: Type 2 errors are common, particularly in studies with small sample sizes or low statistical power.

Myth: Type 2 errors are rare

• Considering multiple testing scenarios
• Data scientists and analysts

A Type 1 error is a false positive, where a test incorrectly detects a real effect or difference. A Type 2 error is a false negative, where a test fails to detect a real effect or difference.

A Type 2 error, also known as a false negative, occurs when a test fails to detect a real effect or difference. In other words, it's a mistake that occurs when a study or test misses a significant finding. Imagine conducting a medical trial to determine the effectiveness of a new treatment. If the trial concludes that the treatment has no significant impact when, in reality, it does, that would be a Type 2 error. This can lead to incorrect conclusions, missed opportunities, and wasted resources.
