DESCRIPTION:Means and standard deviations based on data on rating scale-dat
 a are not independent of each other: Means around the scale’s center can
  coincide with larger standard deviation than means towards either limit o
 f the scale. Heathers et al. (2018) plot all combination of means and stan
 dard deviations for a sample of ten on a 5-point scale and observe that th
 e results scatter in the shape of an umbrella. Based on the Bernoulli dist
 ribution\, we developed a simple formalization of these umbrella restricti
 ons that generalizes across samples sizes. We introduce that formalization
  and explore its implications to statistical power and meta-analytical eff
 ect heterogeneity. Further\, we describe how the formalization adds to the
  error-detection toolbox.
