time series
Chronological data points
A time series is a sequence of data points recorded at successive intervals—hourly temperatures, daily stock prices, annual GDP figures.
The ordering matters: time series analysis looks for trends, cycles, and patterns that unfold over time.
The time series showed a clear upward trend over the decade.
