Question: Researchers who conducted a study of brain activation and romantic love divided their analyses into two groups (Aron et al., 2005). Some analyses-those for which they had developed specific hypotheses prior to data collection-used a p level of 0.05. The rest of the analyses used a p level of 0.001.
a. Explain why the researchers' plan to have different p levels for the two groups was a wise one.
b. Suggest one method by which the researchers could have come up with a p level of 0.001 as their cutoff.
