This means that .025 is in each tail of the distribution ... WebWhat does p value mean? A p value refers to the measurement of the value of probability that an observed difference could occur by chance. There exists an inverse relationship among p value and statistical significance. A low p value will correspond to the greater statistical significance of the observed difference and vice versa.
