Answer:

cyclical variation

Explanation:

Cyclic variation refers to recurrent variation in time series that lasts two or more years and is not gradual in amplitude or length.

These variations are known as oscillation motions, which fluctuate after more than a year.

  • Most time series in business and economics show such cyclical variation. There is a four-cycle period defined by the business cycle:
  1. prosperity
  2. decline
  3. depression  
  4. improvement.
