I am so depressed now that I have to make some desision now. Sigma does fine but I still dream about the SD!

Sigma Disaster for which the SD has finally, after many long years provided a cure.

YOU GUYS ARE A BUNCH OF SLY DOGS!! Seriously, People shouldn't put Sigmas Down. There way better to shoot than thoughs Silly Derrengers. I wonder if any of the State Dnr's will buy them. Simple Decision if you ask me. Maybe them Sh$%*$ Democrats have all these answers. Nahh, They all Sin like the Devil.

How To Calculate Standard Deviation82
rate or flag this pageBy sonia



First, you need to determine the mean. The mean of a list of numbers is the sum of those numbers divided by the quantity of items in the list (read: add all the numbers up and divide by how many there are).

Then, subtract the mean from every number to get the list of deviations. Create a list of these numbers. It's OK to get negative numbers here. Next, square the resulting list of numbers (read: multiply them with themselves).

Add up all of the resulting squares to get their total sum. Divide your result by one less than the number of items in the list.

To get the standard deviation, just take the square root of the resulting number

I know this sounds confusing, but just check out this example:

your list of numbers: 1, 3, 4, 6, 9, 19

mean: (1+3+4+6+9+19) / 6 = 42 / 6 = 7

list of deviations: -6, -4, -3, -1, 2, 12

squares of deviations: 36, 16, 9, 1, 4, 144

sum of deviations: 36+16+9+1+4+144 = 210


divided by one less than the number of items in the list: 210 / 5 = 42

square root of this number: square root (42) = about 6.48

Not slamming Sigmas-still like mine. Just something in my mind that leaked out through my slow typing fingers. Enjoy and please add to list as you wish!

SD = "Sigma's Done"

SD.....SAD DAY.....
I welcome the SD, but I am a little sad that it has to have the wide spaced serrations on the slide fore and aft (read ugly). I also want the stainless silver color slide. I would welcome the model SD more if they had just left those two things as they were on the Sigma-I know this is a marketing gimmick to make it look much unlike the Sigma to grow the interest of new potential buyers, but I still love the looks of the 40VE.
