Document Summary

To be important a study must be replicable. External validity comes from how, not how many. Review: external validity: we can generalize to other people as well as to other settings. Goal: to make a claim about a population. Interrogating the three types of claims using the four big validities. Goal: to test a theory rigorously, isolate variables. Internal validity - frequency claims are usually not asserting causality, so internal validity is not relevant. Internal validity - people who make association claims are not asserting causality, so internal validity is not relevant to interrogate. A researcher should avoid making a causal claim from a simple association, however (see chapter 8). I don"t think this study is important because the methods had nothing to do with the real world. I reject this study because they didn"t use a random sample. This is a bad study because they used only north americans as participants.
