Morphology

weighted + average

The phrase is straightforwardly compositional: 'weighted' indicates that some values carry more influence and 'average' is the representative number, so the meaning 'an average where contributions are scaled by weights' is directly derivable from the constituents. This construction is common in many languages and follows transparent adjective + noun logic, so a B1 learner who knows both words will likely understand it.

Etymology

Weighted average comes from the image of a balance scale: some items are heavier, so they count more when you find an average. The word weighted means each value has a 'weight' that shows its 'importance', so the final number is moved more by larger or more important values.
