Diffusion of Power-Related Data in Communication: A Research Note

Statistical power is viewed as an innovation, and its development within the communication discipline is examined. The results of three statistical power analyses are reported, and a comparison of the resultant power estimates is conducted. Using the medium population effect as a baseline, the average statistical power exhibited in communication research has increased. Although it is too early to identify statistical power analysis as the primary antecedent, these surveys have certainly performed a knowledge function in the diffusion of power-related data.
