The video tutorial explains common time series patterns, including trends, seasonality, and cyclicity. Trends indicate a general increase or decrease over time, while seasonality involves regular patterns related to the calendar. Cyclic patterns differ as they do not have a fixed period. Examples include Australian electricity and clay brick production, U.S Treasury bills, and Hudson Bay lynx populations. The tutorial emphasizes distinguishing between seasonal and cyclic patterns, as they require different modeling approaches.
