Detailed explanation-1: -Calculate the percent defective. It is the number of defects divided by the sample size, multiplied by 100. So, if one tool is defective out of a sample size of 1, 000, your percent defective is 0.1 percent.
Detailed explanation-2: -The percent defective is the number of values of a variable (expressed as a percentage) that fall outside of some user specified tolerance limits.
Detailed explanation-3: -Defects Per Unit (DPU) DPU measures the average number of defects per every product unit. It’s found by dividing the total number of defects found by the number of units. For example, if 30 units are produced and a total of 60 defects have been found, the DPU equals 2.
Detailed explanation-4: -Control charts dealing with the number of defects or nonconformities are called c charts (for count). Control charts dealing with the proportion or fraction of defective product are called p charts (for proportion). There is another chart which handles defects per unit, called the u chart (for unit).
