Sample question
A meteorologist plots a time series of total rainfall recorded each quarter at the Brisbane Aero station over five years. The plot shows a repeating pattern in which Summer values are consistently high and Winter values consistently low, with the same shape recurring every 12 months. This repeating within-year pattern is best described as the:
- cyclical component
- seasonal component
- irregular component
- long-term trend component
Show the worked answer
Answer: B
A pattern that repeats over a fixed, known period of one year (the four seasons) is the seasonal component. Cyclical patterns repeat over periods longer than a year with no fixed length.
