We generalize the notion of mean value by considering fucntions of the form:

We term these functions quasi-means and we propose a characterization based on two associative operations -- corresponding respectively to combination of individual coordinats and combinations of aggregate values. We then show that the only homogenous quasi-means are quasi-linear, and discuss a further extension.
