Question

Quizplus · Accepted Answer

A .02 level of statistical significance means that there is only a 2% probability that the observed difference or relationship is due to chance. Therefore, B is the correct answer. A is incorrect because a 1% probability would require a higher level of significance (e.g. .01). C and D are incorrect because they suggest that there is a higher probability of chance (e.g. 98% or 100%), which is the opposite of what is indicated by a significant result.
