The error is
|x-mean(x)|
so the mean error is
mean(|x-mean(x)|)
I think this is what is intended, but usually this quanity is called the mean absolute deviation.
The other posibility is if you knew for each sample what should have resulted then it could mean
mean(x_experimental-x_actual)
or
mean(|x_experimental-x_actual|)
Can't you look up exactly what was "mean error" means?
