Analisi: osservato contro atteso

Each statistic on this page is shown next to the value you would expect if the draws were purely random. The expected values are calculated exactly (closed-form formulas over all 1,533,939 combinations), not simulated. The result in advance: everywhere, what we observe stays within the range of chance.

How close together are the five numbers?

The linear span is the distance from the smallest to the largest number (end positions included). The circular span reads the numbers 1 to 47 on a circle where 47 touches 1: the draw 4, 5, 7, 45, 47 is then no longer spread over 44 positions but concentrated on 10. The bars show the distribution of draws by span, observed and expected.

Le estrazioni più compatte

A circular span of at most 10 has a probability of 0,39% for a random draw. We therefore expected 2,7 such draws; there were 1.

Cosa si ripete dall'estrazione precedente?

For each draw, we count how many of its five numbers were already in the immediately preceding draw. The expected distribution is hypergeometric: 5 drawn from 47, of which 5 are marked.

La schedina come mappa di calore

The 47 numbers in rows of ten. The darker the cell, the more often the number was drawn. The expected value is the same for all; the differences are the normal spread of a binomial distribution.

The gap between the rarest and the most frequent number looks large, but it is exactly what you expect from 47 independent counts. Over the last 100 draws the relative spread is even larger because the sample is smaller.

Quanto resta assente un numero?

For each number we measure the gap in draws between two appearances. If the draws are independent, this gap follows a geometric distribution with probability 5/47 ≈ 10.6% per draw: mean 9.4, and long absences are not rare, they are the rule.

The longest absence in the data is 79 draws. The probability that a given number stays absent that long is 0,02%; with 47 numbers it is bound to happen eventually. The longest current absence is 37 draws. A number that has been absent for a long time is therefore not "due": the balls have no memory.
