Correlation analysis of telecom bank card fraud

At present, telecommunication fraud crimes continue to occur frequently, causing huge economic losses. This study aims to explore the correlation between telecommunication fraud and given indicators, and determine whether (whether the bank card transfer transaction occurs in the same bank) and (whether the transfer transaction is online) are significantly correlated with telecommunication card fraud. Eight indicators were tested, and the results showed that all indicators did not meet the normal distribution. Then, using Spearman correlation analysis, it was determined that (the distance from the last transfer transaction) and (the ratio of the current transfer transaction amount to the last transfer transaction amount) had a low correlation with whether there was telecommunication fraud. Finally, the chi square test was used to determine the indicators that were significantly correlated with telecommunication fraud, and it was concluded that there was a significant correlation between (online transfer transactions) and whether there was telecommunication fraud.
