Upgrade to ProYou are a Fraud Analytics Engineer at Wells Fargo. The fraud detection team needs a statistical baseline for identifying unusual transaction amounts. For each account, you must compute the interquartile range (IQR) of transaction amounts and flag any transaction whose amount falls outside the expected bounds as anomalous. This IQR-based method is a standard first-pass filter that surfaces transactions worth investigating further.
