BENFORD ANALSYSIS<br />

FIG 25. VOTO SOCIAL – User Interface<br />

The Benford test applied to the 1 st digit is used to validate a<br />

population and numbers and detect anomalies and potential<br />

fabrication of information. This test was used in financial<br />

systems and is also used to detect voting fraud. The Test<br />

follows the “Benford Law’ distribution where each digit<br />

probability is Log(N)-Log(N-1). The computation is quite<br />

simple and requires the use of the command LEFT using<br />

“LEFT (cell_id, 1))” and applying the frequency counter<br />

with l “COUNTIF(range, id of integer)”.<br />
