Part A. Type 1 and Type 2 Errors Make your decision: Is there a type 1 or type 2 error in the research examples? Research Examples Nope! Type I Type 2 error error Scenario 1: A researcher conducted a study on mindfulness and employee well-being. The researcher concluded that mindfulness meditation increased employee well-being. However, in reality, this was not true . Scenario 2: A researcher conducted a study on therapy dogs and academic performance. The researcher concluded that there was no difference in academic performance (and was correct). Scenario 3: A researcher conducted a study on caffeine and sport performance. The researcher concluded that caffeine did not influence sport performance. However, in reality, it did increase sport performance. Scenario 4: A research conducted a study on vacation and employee well-being. The researcher concluded that a week vacation increased employee well-being (and was correct). Remember: Type 1 error = rejecting the null when it was actually true . Type 2 error = failing to reject null when it was actually false
