Abstract
The aim of this study is to construct an Exponentially Weighted Moving Average (EWMA) control chart for monitoring the quality characteristics of Bic Pen. The quality characteristics under study are Pigment (gm), Ferrous Sulphate (gm), Golic Acid (gm), and Tartaric Acid (gm). The study made use of a random sample of four Bic Pens selected from a packet of 50 pieces of pens for a subgroup of twenty. The data was analyzed using EWMA chart and the result of the analysis shows that all the quality characteristics under study were within the control limits. Trial control limits were recommended for future production of Bic Pen by Nigeria Ball Point Pen Industries (NIPEN), Plc....
