U chart is used when you have Defects data with a Variable Sample Size. In a U chart, the UCL and LCL will vary with changes in the sample size Average Defect Count (u-bar)Calculate the average defects (for all samples) and enter the value in this cell.Sample Size (in the last sample)Control Limits may vary depending on the sample size. Generally, the last sample size is used. But you may enter any other sample size as wellNumberUpper Control Limit for ith sampleNumberLower Control Limit for ith sampleLower Control Limit for ith sampleControl Limits Not ApplicableControl Limits cannot be calculated since a negative or a zero average defect count (u-bar) was entered. Enter a value greater than zero Δ
