### sense in the lessons

In science experiments, the baseline is what you measure before you change anything, so you can see how much changed. In school tests, a «baseline test» shows what a pupil knows at the start of the year. In tennis lessons, players serve from behind the baseline.

### note

Countable: a baseline, baselines; sometimes spelt «base line». In maths and science problems, the change = new value − baseline: if the baseline is 20 and the new value is 26, the increase is 6. Do not confuse with «bassline» (the low notes in music).
