sigma is the short for sums for example, lets say you want to add 1+2+3+4+5+6.................+99+100 it's a problem writing every single term, right? so if the sum it's a pattern like the example above, you can write it in sigma notation search it up on the internet and find some simple examples because i am not the best explainer in the world =) **Sigma is also used in statistics to mean "standard deviation."
z = (x-mu)/sigma So x = sigma*z + mu = 3m*(-3) + 25 = -9m + 25
Let x denote the values of the variable in question. Suppose there are n observations. Let Sx = the sum of all the values. then the mean of x, Mx = Sx/n Let Sxx = the sum of all the squares of the values. The Vx (= the variance of x) is Sxx - (Mx)^2 and sigma(x) = sqrt(Vx). Therefore one sigma deviation, relative to the mean, = Mx - sigma(x), Mx + sigma(x).

I regret that the browser that we have available to us will not accept any mathematical symbols - such as sigma, of any super/sub-scripts.

Sigma Sigma Rho was created in 1998.
Omega and sigma are just for notation, although omega usually represents some sort of angular frequency, which is usually multiplied by the complex number "j." In short, it can, but it's not exactly correct; sigma represents the real component and omega represents the imaginary component.
