Does a small p value give strong evidence
WebStatistics and Probability questions and answers. Why do very small p-values indicate that the evidence against the null hypothesis is strong? (1 point) A) Because the p-value is the probability that the null hypothesis is true.

WebNov 20, 2024 · If the null-hypothesis is true, p-values are uniformly distributed. This means it is just as likely to observe a p-value of 0.001 as it is to observe a p-value of 0.999. This indicates that the interpretation of p = 0.001 as ‘strong evidence’ cannot be defended just because the probability to observe this p-value is very small.
