Psychologists commonly use a level of significance of .05 (or 5% chance) when assessing whether their results are due to chance. This level of significance provides a reasonable balance between minimizing the probability of making a type I error (rejecting a true null hypothesis) and maximizing statistical power to detect true effects.
