PSY 301 Chapter Notes - Chapter 14: Publication Bias, External Validity
Document Summary
Replicable: same results have actually been reproduced. Repeat an original study as closely as they can to see. Replicated whether the effect is the same with the new data. Researchers explore the same research question but use different procedures. Researchers replicate their original experiment and add variables to test additional questions. About the extent to which published studies can be replicated. The open science collaboration replicated 100 studies and only 36% produced same results. Not replicated in the exact same way, results may be wrong, problems with the original study, flukes. Open science: practice of sharing one"s data and materials freely so others can collaborate, use, and verify the results. Preregistration: scientists can pre register their study"s method, hypothesis, or statistical analysis online, in advance of data collection. Scientific literature: series of related studies conducted by various researchers that have tested similar variables. Meta-analysis: mathematical summary of a scientific literature. File-drawer problem: publication bias affects which articles are punished.
