5.3 Analysis of Variance in parameters based on pooled data
Variance in data was observed in each set of experiments due to a number of factors. These factors include stirrer speed, oxygen content, and the different sizes in air stones.
From the ANOVA illustrated in Figure 1, the sources X1, X2, X3, X4 are oxygen flow rate, stone size, stirrer speed, and groups respectively. It is seen that the largest variance occurs at the stirrer speed parameter, with
