Extending recent work on stress fluctuations in complex fluids and amorphous solids we describe in general terms the ensemble average [Formula see text] and the standard deviation [Formula see text] of the variance [Formula see text] of time series [Formula see text] of a stochastic process t) measured over a finite sampling time [Formula see text]. Assuming a stationary, Gaussian and ergodic process, [Formula see text] is given by a functional [Formula see text] of the autocorrelation function h(t). [Formula see text] is shown to b
