WebThe calculations for X-Bar (), R, R-Bar and S are basic to the GainSeeker SPC system. The methods for calculating each depend on the subgroup size of the sample. Calculating X-Bar and X-double bar = the average of the values in a subgroup = the average of the averages. WebCompute X bar and S values Measure the average of each subgroup i.e X bar, then compute the grand average of all X bar values. This will be the center line for the X bar chart. Compute the standard deviation of each subgroup, then measure grand averages of all standard values ie S bar, and this will be the center line for the S chart. the perfect wave online subtitrat
