Question

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.

Answer 1

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!

Answer 2

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.

Answer 3

Your answer is correct. When the purpose of sampling is to detect when a process becomes too variable, the chart of choice is an R chart. The R chart, also known as the range chart, is used in statistical process control to monitor the variability or dispersion of a process. It plots the range of values within each subgroup or sample. By monitoring the range over time, you can detect when the process is becoming more variable or less predictable, which indicates that it may be going out of control.
