Scholars have noted that data mining is used as a means for detecting fraud, assessing risk, and product retailing.  Data mining involves the use of data analysis tools to discover previously unknown valid patterns and relationships in large data sets (Barreto, 2015, Collins, 2012 and  Hoath, 2013).
