4. What is a reason for paying more attention to P VALUES over effect sizes?
If you have controlled your experiment even small effects are interesting
Because small experimental biases can give rise to a high p if n is high, not a'real result'
5. What is the issue with multiple comparisons?
If you do lots of tests on a single dataset/multiple studies some will be signif only by chance. e.g probability of getting a posi result x 13 experiments...likely that one will be significant
A post hoc definition of success. Not defining predictions before the experiment
Bad data are not included in the study and people being reluctant to publish negative results/replications
