Statistical Quality Control On Gulder Lager Beer (A Case Study Nigerian Breweries PLC Aba)
ABSTRACT
The quality of a product is indicative of the level of satisfaction derived by the consumer of the
product as well as the quantity demanded of the product. The higher the demand, the higher the
quantity of a product sold and the higher the profit made by a company. Thus, maintaining or
controlling the quality of a product is an issue of major concern to the company. This study was
primarily carried out to check if the quality characteristics of Gulder Lager Beer are under statistical
control. The control chart for mean (x-chart) and control chart for standard deviation (s-chart)
were constructed for the quality characteristics (alcohol percentage by volume, temperature, head-
space air, pressure). It was observed that alcohol percentage by volume was not in a state of quality
control. Hence revised control limits were constructed based on the derived limits.
