presents the results of the Apriori algorithm analysis.
Three correlation rules were identified beyond 80% (calculated according to the number of antecedent and consequence items).
These three correlation rules covered 153 customer-complaint records in total (with rule 1 covering 94 complaint records, rule 2
covering 12, and rule 3 covering 47), which represents 31% of the
500 customer-complaint records included in the study.
