What is meant by space average?

What is meant by "space average?"

What is meant by the term "space average?"


I think my understanding would be similar to taking the time average of something, i.e. using an integral:
$$\frac{1}{b-a}*\int f(t) dt$$

Where the integral goes from a to b.

But instead t would be replaced with x (the position), and the function adjusted appropriately. Is this right?

Yes it is, at least for 1-dimensional space.
