It is based only a 'yes-or-no' type of conclusion based on whether the item complies with the specification. P - Chart, np - Chart and C - Chart are the control charts for attributes. For this purpose we need to define 'defect' in the item - i.e. a presence or absence of a particular characteristic. Then we just need to draw samples and count the number of defective units in each sample. Control Chart for Fraction Defectives' or 'Proportion of Defectives i.e. P - Chart Steps 1) Calculation of fraction defection of each of the samples. p = (No. of defective units in the sample)/(Sample size) Or p = np/n 2) Calculation of average fraction defective P(bar) = Σnp/Σn 3) Calculation of control limits UCLP = P(bar) + 3√[P (1 – P)/n] CLP = P(bar) LCLP = P(bar) – 3√[P (1 – P)/n] Problem/Case: The following figures give the number of defective units in 20 samples each containing 2000 items: 425, 430, 216, 341, 225, 322, 280, 306, 337, 305, 356, 402, 216, 264, 326, 126, 409, 193, 280, 389 Construct P-Chart and state your conclusion about the process.
