Quizplus · Accepted Answer

R-charts are used to measure changes in the degree of variation in a production process. They plot the range of a sample of measurements, indicating how much variability there is within each sample. This helps identify when the process is experiencing unusually high or low levels of variation, which may be a sign of problems in the production process.
