p value is the probability of obtaining the observed data or more extreme data assuming the null hypothesis is true. If the p value is less than the significance level (usually 0.05), it suggests that the observed results are unlikely to occur by chance alone, which leads to rejection of the null hypothesis. Therefore, p value is important in determining the statistical significance of the results and whether they support or reject the hypothesis being tested.
