Which graphical tool would you use to analyze process flow?

The flow chart is the appropriate graphical tool for analyzing process flow because it visually represents a sequence of steps and decisions involved in a process. By using standardized symbols, a flow chart allows you to depict tasks, inputs, outputs, and decision points, which helps in understanding and optimizing the workflow. This tool is particularly useful for identifying bottlenecks, redundancies, and areas for improvement within the process.

Other graphical tools, while useful in their respective contexts, do not focus specifically on process flow. A histogram provides a representation of the distribution of data points across different ranges, a scatter diagram illustrates the relationship between two variables by plotting points on a Cartesian plane, and a run chart displays data points over time to show trends. However, none of these tools effectively maps out the sequential steps and interactions that a flow chart does, making the flow chart the best choice for analyzing process flows.
