What do these numbers show?

Liczba lat w zestawieniu: 70, łącznie 6 540 losowań.
Największe odchylenie pojedynczej liczby przypada na rok 2017: max |z| = 4,860 przy N = 156 losowań (liczba 34).
Lata z małą próbą lub bez losowań są oznaczone w ostatniej kolumnie tabeli; ich miary opisowe zostają.

These are historical data. Each draw is independent of previous draws, so these numbers do not tell us what will be drawn next.

How do I use this page?

Wybierz wiersz roku, który Cię interesuje.
Porównaj miary T i max |z| z liczbą losowań N w tym samym wierszu — mały N daje większe wahania.
Kliknij nagłówek kolumny, aby posortować tabelę; drugie kliknięcie odwraca kolejność.

What this page does not do: nie wskazuje przyczyny odchyleń i nie przewiduje kolejnych wyników.

Methodology

N is the number of draws in that year. All measures in the row refer only to that year's history.

T measures the total deviation of all numbers' hit counts from the expected value under the equal-chance model: the larger T is, the further the yearly counts stray from a uniform distribution.

df is the number of degrees of freedom for this measure — one less than the numbers in the pool.

max |z| is the largest single standardized deviation among all numbers, and "number" indicates which number it belongs to. When counts are tied, the lower number is shown.

Don't compare years with different N as if they were identical trials: with a small N the same differences in hits produce a larger T and max |z|. The deviation in the table is a fact from the history, not a determination of its cause.
