POPH192 Lecture 24 - Chance II

Question 1

what are p-values?

Answer 1

probability of getting the study estimate (or a study estimate further from the null), when there is really no association, because of sampling error (chance)
-uses the logic of hypothesis testing

Question 2

what does a low probability indicate?

Answer 2

if the probability is really low, then it is unlikely that the estimate is due to sampling error (chance)
