The relationship between the two groups was found to be statistically significant at the p<0.05 level.
WebThe p-value indicates how probable the results are due to chance. p=0.05 means that there is a 5% probability that the results are due to random chance. p=0.001 means that the chances are only 1 in a thousand. The choice of significance level at which you reject null hypothesis is arbitrary. Conventionally, 5%, 1% and 0.1% levels are used.
