Yeah its a bit confusing tbh as I don't have much maths understanding.
But I been playing around with excel to try and understand it like entering 1, -1 stdev = 1.41, and 1 -2 = 2.12
So from that and google, I understand its how much the members of a group differ from the mean value for the group.
And I assume mean is 0? As in 1,1 = 0
If I understand the basics correctly.
