Managers using evidence-based management (EBMgt) use data that exist in their organization to draw inferences and make decisions. This process is prone to a number of errors, including the small-numbers problem, measurement unreliability, range restriction, and confounding.

Recommended procedures include statistical corrections and computation methods that make data more interpretable as well as changes in the way data are reported and aggregated within organizations.
