Sensitivity Analysis

Process to determine how outputs of a methodology differ in response to variation of the inputs or conditions.

Sample Usage: The sensitivity analysis showed that the population variable had the largest effect on the output of the model.


  1. When a factor considered in a risk assessment has uncertainty, sensitivity analysis examines the effect that the uncertainty has on the results.
  2. A sensitivity analysis can be used to examine how individual variables can affect the outputs of risk assessment methodologies.
  3. Alternatively, sensitivity analysis can show decision makers or evaluators the impact or predicted impact of risk management alternatives.
