Time Series 

A time series is a sequence of data or observations, measured at certain points in time and arranged chronologically. Visually, it is a curve that evolves over time.

Components of a time series

Trend

The long-term tendency of a series to increase or decrease (increasing trend or decreasing trend).

Seasonality

The periodic fluctuation in time series within a given period. These fluctuations form a pattern that tends to repeat from one seasonal period to the next.

Irregular movement

The movement that remains after accounting for trend, seasonal and cyclical movements; random noise or error in a time series. 

Personal Conclusions

The class was productive and we were able to learn and understand a range of time by looking at some examples and analyzing their components.

Task

Practising what you have learned.
