I know the symbol "δ" stands for standard deviation in statistics.

That symbol is a Greek letter called a lower case sigma.

In statistics it is usually used to represent parametric standard deviation of a population, while S generally represents sample standard deviation.

RE:

What does δ stand for in statistics? ?

Is it standard deviation or something else?

Google totally sucks with this...

δ helppppppp

δ is a delta, σ is a sigma. a δ (delta) that usually represents a discount factor (how much a value is decreased);

σ is the standard deviation of a distribution (how varied the observations of a sample are).

Δ Time is the change in time. T2 - T1 = ΔT
