Cultural Dictionary

In statistics, a number that expresses the probability that the result of a given experiment or study could have occurred purely by chance. This number can be a margin of error (“The results of this public opinion poll are accurate to five percent”), or it can indicate a confidence level (“If this experiment were repeated, there is a probability of ninety-five percent that our conclusions would be substantiated”).
