Reproducible Science

• File-draw problem: suppressing the true evidence is not in support of the alternative hypothesis by disregarding outlier participants
• Running a repeated variations ofstatistical tests to manipulate the p-value to establish significance is called?

  p-hacking
• The plausibility hypothesis is crucial as it establishes the theoretical underpinnings for likely (chance) the hypothesis testing.
• A researcher posts a detailed plan for how they will collect and analyse data, before beginning data collection, to an online repository, what concept does this relate to?

  Preregistration of research
• Replication allows researchers to arrive at a consistent conclusion of methods were robust through mandatory preregistration
• What are the steps we should take when analysing research?

  1. Look out for preregistration and open data materials
  2. Be critical of p-values and replications in meta-analyses
  3. Be skeptical
