The average values of the experts’ opinions are statistically compared with the FCM’s
results. The behavior of the FCM’s results has been examined against the experts’ opinions in the
plant by analysis of variance (ANOVA). A two-sample t-test has been conducted to test the
equality of means (`a: > = ?). Prior to t-test, the equality of variances (`a: b>
? = b>
?
) has also
been tested by F-test. The results of the ANOVA are summarized in Table 8. It is concluded that
there is no difference between the FCM’s results and the experts’ opinions at confidence level of
0.95 (α=0.05).
