PPT-Section 4.3 Determining Statistical Significance

Review The smaller the pvalue the stronger the evidence against the null hypothesis stronger the evidence for the null hypothesis If the pvalue is low then it would be very rare to get results as extreme as those observed if the null hypothesis were true This suggests that the null hypothesis is probably not true .
