Analyze distributions and detect anomalies

What is Distribution Analysis?

Distribution Analysis helps auditors understand how numerical values are spread across a population, highlighting concentration, tails, breakpoints and unusual observations that may deserve review.

Why is it useful?

Comparing quantile ranges helps determine whether values follow a consistent distribution or whether specific segments show unusual concentrations, gaps or deviations that may require audit review.

When to use it

This method is useful in audit, internal control and risk analysis when reviewing large sets of numerical values such as invoices, payments, orders, balances or operational measurements.

How the workflow works

The tool provides a guided workflow to upload a dataset, select the numerical analysis column and prepare the data for distribution-based analytical review.

Key steps

  • Upload your data: import an Excel file containing structured numerical values.
  • Select the analysis column: choose the numerical field that should be used for the distribution analysis.
  • Run the analysis: calculate distribution bands and review the results to identify critical intervals and unusual observations.

The resulting analysis is intended to support audit work by highlighting areas that may deserve further investigation, while preserving the need for professional judgement.
