This episode explains time series analysis and forecasting, which focus on predicting values that evolve over time. Key concepts include trends, which capture long-term movements; seasonality, which reflects repeating cycles; and drift, which occurs when patterns change unexpectedly. For certification exams, learners should understand how time-dependent data differs from static datasets, requiring specialized techniques such as ARIMA models or recurrent neural networks.

Examples illustrate practical uses. Retailers forecast demand to manage inventory, utilities forecast load to stabilize power grids, and IT operations forecast traffic to prevent outages. Troubleshooting challenges include sudden disruptions, such as economic shocks or system failures, which break historical patterns. Best practices stress validating models on recent data, incorporating domain knowledge, and monitoring for drift over time. Exam scenarios may ask learners to identify whether observed changes reflect seasonality, drift, or noise. By mastering time series forecasting, learners prepare for both exam items and practical roles where anticipating the future is central.
