U Chart Notes:
U chart is a type of attribute control chart which is used when the sample size is greater than 1. It shows the average number of non-conformities in a unit. When using u chart, the size of one subgroup can be different from another. In case of u charts, items in a subgroup can have multiple defects. Control limits for u chart are established using the already defined formula. Usually, lower control limit of a u chart is calculated to be a negative number, so zero (0) is used as the lower limit of u charts. U charts are plotted based on Poisson distribution.
