Document Summary
Ch 14 - replicability, generalization, and the real world. To be important, a study must be replicable. There is direct replication, conceptual replication, and replication-plus-extension. Even if the previous study had a statistically sig result, you should still conduct the study again. In direct replication - exact replication, researchers repeat an original study as closely as they can to see whether the original effect shows up in the newly collected data. You can"t control everything such as time of year or who administers the test but that"s okay. Ex) ppl rating strangers based of id #s that matched their own birthdays. Researchers value other types of replication instead of direct replication. In a conceptual replication - researchers study the same research question but use diff procedures. The variables in the study are the same, but the procedures for operationalizing the variables are diff. Ex) using diff size containers to serve popcorn in, diff snacks instead of pasta, etc.
