Australia Saturday Lotto Bell Curve Statistics

This page displays a Bell Curve, also known as a Normal Distribution or Gaussian Distribution, for Australia Saturday Lotto. It shows how frequently the winning numbers add up to a certain sum.

The grey curve on the graph is the expected Bell Curve, which displays how often each sum should have appeared in all draws to date. For example, if there is a 1 in 100 probability that the winning numbers will add up to a certain sum in any given draw, that sum would be expected to appear 10 times over 1,000 draws. The expected Bell Curve is symmetrical and has one mode, which coincides with the mean and the median.

This is overlaid with the actual number of times each sum has appeared in all draws to date (the blue bars). This will match the expected Bell Curve more closely as more draws take place. The curve for draws with a limited history may look more erratic.

Main Numbers:

The data is further laid out in the table below. It shows, for each of the sum totals, how many possible number combinations there are, the expected number of times that each sum should have appeared in all draws to date, and the count of how many times it has actually appeared. The final column shows if a particular sum is overdue. A sum is regarded as overdue if it hasn't appeared for twice the number of draws it is expected to. For example, if there is a 1 in 100 probability of a particular sum appearing, it will be labelled overdue if it hasn't appeared for 201 draws or more.

Some lotteries have undergone rule changes in the past that have affected how many main numbers are drawn. To remain consistent, data is taken only from draws that used the same matrix that is currently in use. This can mean that the statistics for some games are limited.

You can find the Bell Curve statistics for the Supplementary numbers below the table for the main numbers.
