Change Details: This story originally asserted that “The closer to zero the <i>P</i> value gets, the greater the chance the null hypothesis is false.” <i>P</i> values do not give the probability that a null hypothesis is false, they give the probability of obtaining data at least as extreme as those observed, if the null hypothesis was true. It is by convention that smaller <i>P </i>values are interpreted as stronger evidence that the null hypothesis is false. The text has been changed to reflect this.
