The peculiar patterns of first digits

Despite seeing numbers all the time only occasionally would one say that a list of numbers seems odd. For this to occur, the numbers are typically highly rounded or implausible (too much of a coincidence). However digit pattern analysis, using a computer, can produce valuable findings not revealed at a mere glance. The most widely cited paper on digit frequencies was published by Frank Benford in 1938. With powerful, low-cost personal computers, Benford´s law can help us to efficiently test the integrity of data. The first step is to assess whether Benford´s law should apply to the data. If the data is expected to conform, then Benford´s law becomes the expected distribution. Conformity means that the actual distribution closely approximates the expected distribution
