Visual Sample Plan (VSP) is a tool that helps ensure the right type, quality, and quantity of data are gathered to support confident decisions and provides statistical evaluations of the data with decision recommendations. Developed with support from the U.S. Department of Energy (DOE), U.S. Environmental Protection Agency, Department of Defense, Department of Homeland Security, the Centers for Disease Control, and the United Kingdom, VSP has more than 5,000 active users. Many statistical sampling designs are available—from random and systematic, to sequential, adaptive cluster, and more. VSP is recommended by many regulators for defensible sampling design and statistical analysis.
