Which of the following can be used to determine whether a sample product is within an acceptable range?

A scatter diagram shows the relationship between two variables, useful for identifying correlation, but not for determining if individual samples are within an acceptable range.

A velocity chart tracks the amount of work a team completes in an iteration, relevant for Agile projects, but not for assessing individual product sample quality against acceptable ranges.

A control chart is a statistical process control tool used to monitor a process over time. It graphically displays data points within upper and lower control limits, allowing a project manager to determine if a process or product sample is stable, in control, and operating within acceptable parameters or if a deviation requires investigation.

A fishbone diagram (Ishikawa or cause-and-effect diagram) is used for root cause analysis of problems, not for monitoring sample data against control limits.
