Morphology

oversample = sample (transparent) = over + sample

The noun denotes an extra or enlarged sample and its meaning is directly predictable from 'over' + 'sample'.

Etymology

Oversample comes from the parts over meaning 'more than usual' and sample meaning 'a small part or example'. So an oversample is an extra set of observations — extra examples taken to make a small group show up more clearly and to make study results more accurate.
