Election forensics are methods used to determine if election results are statistically normal or statistically abnormal, which can indicate electoral fraud.[1] It uses statistical tools to determine if observed election results differ from normally occurring patterns.[2] These tools can be relatively simple, such as looking at the frequency of integers and using 2nd Digit Benford's law,[3] or can be more complex and involve machine learning techniques.
