Careful interpolation yields useful information: tips for getting extra resolution in measurements
Article Abstract:
Readers of pointer-type scales should interpolate, or estimate readings between dial divisions, to a tenth of a division. In doing so, they will probably add substantial statistical significance to the resulting data. When learning how to interpolate, it is important to be aware that you may see the scale at an angle and wrongly interpret it if your eye is not aligned with the pointer. It is worth using a protractor or a computer drawing package to make scales with practice readings at various positions between divisions. Interpolation is also important with digital meters, as there may not be as many digits of resolution as are required to extract the full significance from the data.
