Data were analyzed in the Weka program using a data set containing 225 different products. Apriori and FP Growth, which are Association Rules algorithms, were tried in order. Since the data set is categorical, the Apriori algorithm did not yield any results. Therefore, the FP Growth algorithm was used and the top 10 rules were given according to the conviction value. The best rule accordingly; a customer who buys Milk, Sweet Relish and Pepperoni Pizza (Frozen) also gets eggs.
