Question

Quizplus · Accepted Answer

A Type I error occurs when the researcher rejects a true null hypothesis (i.e. the null hypothesis is that there is no improvement in VO₂max after the intervention), and concludes that there is a significant difference (i.e. an increase in VO₂max) when there is no actual difference present. Therefore, the researcher is reporting an increase that did not actually occur, indicating a Type I error.
