Answer: BExplanation: A control chart is a really valuable tool for visualizing how a process is doing over time. By taking one measurement after another and plotting them on a line chart, you can get a lot of great information about the process. Every control chart has three important lines on it: the mean (or the average of all data points), an upper control limit and a lower control limit. Any time you find a data point that's either above the upper control limit or below the lower control limit, that tells you that your process is out of control. And that's a really useful thing to know! It tells you that you need to take a close look at the process and make some change to the way the team does their work.
