Standard Deviation Filter

Menu: Filters  Standard deviation

Filter Standard Deviation offers parameters to set the minimum and the maximum values of standard deviation calculated for the average value of all ticket numbers.

In general, if the first and the last ticket number are close to each other then standard deviation value is very low (for example ticket 1, 4, 5, 6, 9, 12 has standard deviation 3.87 or ticket 34, 35, 42, 43, 44, 45 has standard deviation 4.76). On the other hand, tickets with numbers distributed into two separate groups have the highest value of the standard deviation (for example ticket 1, 4, 5, 6, 46, 49 has stddev 22.55 and ticket 3, 7, 41, 43, 47, 49 has stddev 20.89).

Note: The tickets mentioned above are from a 6/49 lottery. Tickets 1,2,3,4,5,6 and 44,45,46,47,48,49 have the lowest possible value of the standard deviation (1.87), ticket with numbers 1,2,3,47,48,49 has the highest possible stddev value (25.21).

Note: The term Standard Deviation is used in several places within the program. These are Standard deviation in Winning Numbers History (page WN History, Summary Table column StdDev(Diffs) and standard deviation labeled as Diffs StdDev in Simulation table on WN History page) and finally standard deviation labeled as StdDev applied for differences between calculated mean number and individual numbers within one ticket, which is also used in this filter window.

Note: You can track how this filter performed in the lottery history on page Statistics Winning Numbers Winning Numbers Table. Furthermore, Winning Numbers Chart page allows you to set parameters for this filter by drag & drop of margins to required position (chart window must be displaying one set of data only - see Options button under the chart window).

When the package is not empty you can click Filter button under the chart to open this filter window and have the filter options preset with values corresponding to chart margins. You must move both margins to enable the Filter button. The actual values of margin positions are displayed at the status bar under the chart window.
