The Last Digit

In a random set of integer values, the last digit should occur with equal probability: 1/10. Deviation from randomness might be legit or might be a sign of artificial interference.

Method Description

Last Digit Analyzer in the Lab

Histogram

The values under study are aggregated by intervals (bins). The aggregated sums are proportional to the heights of the bars. Most of the expected distributions are expected to be unimodal.

Scatter-plot

Scatter-plot diagram visualizes correlations of two chosen values. Each pair of values, most often they are a subset of voting results by PECs, corresponds to a point whose coordinates are equal to the values. Uniform distributions are expected, without clusters, lines, abnormalities and artefacts.
