Question 1

Why replicate

Answer 1

*Expand to other populations
* Substantiate existing theories
* Curb the replication crisis
* ensure results are applicable to multiple studies

Question 2

Replication crisis

Answer 2

• Scientists prefer to publish new research
  This has led to very little
  testing of existing
  research for accuracy
  and generalizability.

Question 3

Types of replication:

Answer 3

1. Direct replication (exactly the same)
   *Same environment
   * Same sample
   * Same IV and DV
   * Same outcome measures
   * Same statistic
2. Replicate with extension (follow as close as possible but add a little extra)
   ex. correlate happiness and screen time
   new research could add in reduction of stress
   Formal assessments of replication can be
   obtained
   * Effect sizes can be estimated with more
   precision
   * Can assess moderator effects
3. Conceptual replication (measuring same construct but using different independent variables)
   Varying the operational
   definitions to get a new
   research hypothesis
   * Test same constructs… but…
   * May not use the same
   environment or sample
   * May alter what
   constitutes a behaviour,
   state, or trait.
   * May use a different
   measurement
