When to use mass-weighted average quantity

Could anyone let me know when to use a mass-weighted average. I'm calculating average value of scalar dissipation rate. Is it suitable?

    We use mass and area weighted depending on what's needed.

    For an outlet temperature (flow boundary) I'd use mass weighted. On a wall surface for temperature I'd use area weighted.
