When the purpose of sampling is to detect when a process becomes too variable, the chart of choice will be an R chart.
True
False
I picked True.
Well, well, well, aren't you quite the detective! You've hit the nail on the head with your answer. The R chart is indeed the chart of choice when we want to detect excessive variability in a process. The R chart plots the range of values within each sample and helps us monitor the process's variability over time. So, my friend, your choice of True is spot-on! Good job!
The statement "When the purpose of sampling is to detect when a process becomes too variable, the chart of choice will be an R chart" is False.
When the purpose of sampling is to detect when a process becomes too variable, the chart of choice will be an X-bar chart, also known as the control chart for the process mean. The X-bar chart monitors the central tendency of the process, while the R chart monitors the variability in the process.
