Average And Range - X-Bar and R: If the sample size is relatively small (e.g., less than 10-15), we can use the range instead of the standard deviation of a sample to construct control charts on X-Bar (arithmetic mean) and the range, R. The range of a sa
Measure the average of each subgroup, i.e., X-bar, and then compute the grand average of all X-bar values. This will be the center line for the X-bar chart. Compute the range of each subgroup, i.e., Range, then measure the grand averages of all range values, i.e., R bar. ...
Find the formula for computing the mean and then work through each step of this computation. Show your complete solution. Explain the difference between a bar graph and a Pareto chart. Explain how closely does the mean value approximates the expectation valu...
Unfortunately, the X-bar chart is poor at detecting drifts (gradual trends) or small shifts in the process. For example, there might be a positive trend in the last ten subgroups, but until a mean goes above the upper control limit, the chart gives no indication that a change has taken...
