PERIOD (INTERVAL)

Statistics Directorate    
Definition:
The time interval of single repetition of a varying quantity of a motion or phenomenon which repeats itself regularly.

Context:
The period is the reciprocal of the frequency. More loosely, the expression is used to denote the time interval or average interval between identifiable points of recurrence, e.g. between peaks or troughs of the series (month, quarter, year).

In GESMES/TS, a period is a time reference. (GESMES/TS User Guide", Release 3).
