Quizplus · Accepted Answer

The P-value for a one-sided hypothesis test is calculated by finding the probability of observing a test statistic as extreme or more extreme than the observed if the null hypothesis is true in only one direction whereas for a two-sided hypothesis test, the P-value is calculated by finding the probability of observing a test statistic as extreme or more extreme in either direction (positive or negative) than the observed if the null hypothesis is true. This means that the P-values for a one-sided hypothesis test are generally smaller than the P-values for the two-sided hypothesis test on the same data.
