Which of the following diagrams is used to display sensitivity analysis data?

A decision tree maps out possible outcomes and their probabilities to evaluate decisions under uncertainty, and is not used to display sensitivity analysis data.

An Ishikawa (fishbone) diagram is a cause-and-effect tool used to identify root causes of a problem, not to visualize sensitivity analysis results.

An influence diagram shows relationships and dependencies between variables in a decision model but is not the standard format for displaying ranked sensitivity analysis output.

A Tornado diagram displays sensitivity analysis results by ranking risk variables from highest to lowest impact, creating a shape that resembles a tornado when displayed horizontally. It is specifically designed to show which uncertainties have the greatest potential effect on project objectives, and it is the recognized standard tool for sensitivity analysis in project risk management per the PMBOK Guide. No other chart type serves this specific analytical purpose.
