Statistical method development is useful when expense, quantity of material, or time is limited, as experiment numbers are significantly reduced. The purpose of this study was to create a statistical model that explains the relationship between viscosity, temperature, concentration, and dilution due to bodily fluids in a pharmaceutical context of carboxymethylcellulose (CMC) solutions. The Graeco-Latin square design was employed to chose data points and Minitab® statistical software was used for data analysis. It was found in this model that concentration and dilution have the greatest effect on viscosity, while temperature has a lesser effect. It was also found that there was some interaction between the variables (temperature, concentration, and dilution) chosen for this study.
