Replication is important because it adds information about the reliability of the conclusions or estimates to be drawn from the data. Repetition vs Replication worksheets and online activities. Students will investigate how the shape and volume of body forms affect heat loss. FREE. Also, boundary conditions become clearer, reducing the potential generalizability space. Even in experimental research, original and replication studies inevitably differ in some aspects of the sampleor unitsfrom which data are collected, the treatments that are administered, the outcomes that are measured, and the settings in which the studies are conducted [11]. Both replication and repetition are important in many fields, but they have different applications. This cookie is set by GDPR Cookie Consent plugin. The ambiguity between disconfirming an original claim or identifying a boundary condition also means that understanding whether or not a study is a replication can change due to accumulation of knowledge.

The term conceptual replication has been applied to studies that use different methods to test the same question as a prior study. Replication is not about the procedures per se, but using similar procedures reduces uncertainty in the universe of possible units, treatments, outcomes, and settings that could be important for the claim. can be found at: Sandy's Science Subjects: 4 When is it time for replication in science? Replication is important in science so scientists can check their work.
