Hi Stan
Could you please explain more about "Standard deviation" & how it is calculated & it's use in Expert Lotto. On page 58 of the user manual it says that ticket 1,4,5,6,46,49, has a stdDev of 22,55. (note:- this has a comma between the 2 and the 5) Yet most of the stdDev in my Expert Lotto progam have figures of around 7.69 to say 13.53 ( note:- this has a decimal point inbetween figures) I realise however that the calcs in the user manual figures are in a 6/49 lotto & mine are from a 6/40 lotto. I'm interested to know a little more about it, as I am wondering whether or not to include the stdDev filter in my weekly lotto calculations? :wand: Many thanks
