Estimating a value between known data values, for example by reading between points along a suitable line on a graph.
Revise: Data TranslationThe line also allows interpolation: estimating between known values. At 75 s, halfway between 60 s and 90 s, the example line gives about 35 °C. This is an estimate from the relationship, not an additional measurement in the original table.
