module of the instrument

Scatter-plot short module


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.

Method Description

Scatter-Plotter in the Lab

Histo short module


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.
