Draw statistics 

The table on the right below is a summary of lottery statistics in terms of total times drawn per ball and is reflected by the graphical results above. See glossary below for terms.

The table on the left lists the last 12 lottery results, each column lists the 7 drawn balls in the relevant week. Where a ball was drawn it is marked with a tick.  The hot balls will have many ticks along their rows, especially in recent weeks.

Also shown is recency rating, a figure derived by weighting the most recent appearances and accumulating over 12 draws. "Ahead/behind" is the difference between the expected frequency and the actual. "Times overdue" is the number of draws since last appearance divided by 7. (Each ball is expected on average to appear once in a period of 7 draws.)

Glossary of Statistical terms used here. 

Minimum ...... The number of times the least drawn (coldest) number has been drawn. It forms the lower boundary of the above graph.

Maximum ...... The number of times the most drawn number has been drawn. It forms the upper boundary of the above graph.

Standard deviation...... a measure of the spread of the number of times drawn. It is expressed as a number which when added and subtracted from the average, provides the range within which most of the results fall. Graphically it is reflected in the fatness of the normal distribution curve shown above.

Total population...... The number of balls drawn since the lottery began on Draw 1. If you multiply each bar height (how many balls in chart f3) by its number of times out , and add them all up - it equals this figure. 

Average or mean......The total number of balls drawn (total population) divided by 49.

Median......The middle number taken from the range of number of times drawn.

Mode......The most popular number of times drawn (i.e by a selection of balls). Where in chart f3 there is no clear indication of the number of times out corresponding to the highest single column - (this is the Mode), this software will return the highest Mode where it finds more than one.
