This will be an example of A)exact replication. B)construct replication. C)systematic replication. D)conceptual replication. 30)Replication A)increases confidence in the validity of findings. B)guarantees construct validity. C)always shows the same results as the first study if the replication is carried out properly. D)is best when the experiment is repeated by the same researcher.. Â
