Morphology

smooth + out

The meaning 'to reduce irregularities or make something even' is directly derivable from 'smooth' (to make even or remove roughness) combined with the particle 'out' (which here signals completion or removal). This compositional pattern is common in English (e.g., 'iron out', 'level out') and would be understandable to a B1 learner who knows both constituents.

Etymology

Smooth out used for data comes from the idea of taking a rough, wavy line and removing small bumps so the main shape is clear—you smooth the curve out. So it means 'reduce random noise or irregularities' in a graph or signal.
