how can you use p value to compare 2 different results of a hypothesis test 
if you have two different results one with a p value of 0 04 and one with a p value of 0 06 the result with a p value of 0 04 will be considered more statistically significant than the p value of 0 06 beyond this simplified example you could compare a 0 04 p value to a 0 001 p value both are statistically significant but the 0 001 example provides an even stronger case against the null hypothesis than the 0 04 the bottom linethe p value is used to measure the significance of observational data when researchers identify an apparent relationship between two variables there is always a possibility that this correlation might be a coincidence a p value calculation helps determine if the observed relationship could arise as a result of chance
