Indicators are crucial to calculate and predict current and future economic performance. There are three types of economic indicators, depending on their timing: leading, lagging, and coincident indicators. Leading indicators signal changes before the economy as a whole changes. Lagging indicators change after the economy changes.
Indicators may be used to check the variation in tolerance during the inspection process of a machined part, measure the deflection of a beam or ring under laboratory conditions, as well as many other situations where a small measurement needs to be registered or indicated.
