time-series
Ordered chronological measurements
A time-series is a sequence of data points recorded at successive intervals—hourly temperatures, daily stock prices, annual GDP figures.
The term functions as an adjective describing analysis methods for such data: time-series forecasting, time-series database.
Understanding patterns across time—trends, cycles, seasonal variations—is the core concern.
