Explanation R chart: The R chart is a control chart that shows the changes of the range value over a period of time and determines variation around the mean by using the sample ranges. The value of the sample range is sensitive to extreme values and is not normally distributed . x ¯ chart : The x ¯ chart is control chart that show the changes of the sample mean or average value over a period of time. It helps to monitor the means of the consecutive samples with a constant sample size n

Question

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
