Time Series

Data that is collected over a period of time is called time series data. A series of seconds, minutes, hours, days, weeks, months, quarters or perhaps number of years may represent time. Often, we draw graphs of time series data as line graphs that can be used to make predictions and draw conclusions.

Example 14
