Question

Quizplus · Accepted Answer

In psychology, the level of statistical significance typically used is .05, which means that there is only a 5% chance that the results obtained occurred by chance. This level of significance is widely accepted and provides a balance between the risk of type I and type II errors. A significance level of .01 is typically used when higher levels of certainty are required, while 0.10 or 0.50 are too high and may produce too many false positives.
