Question

Quizplus · Accepted Answer

Type II errors occur when the null hypothesis is not rejected when it should have been. This can happen if the measures used are too restricted in range, which can lead to a lower variability in the data and make it more difficult to detect significant differences. Using a stronger manipulation or ratio level measurement are not directly related to Type II errors.
