3. 4. Identifying patterns and trends in data

Identifying patterns and trends in data involves examining the dataset for consistent behaviors or recurring phenomena. This process is crucial for making informed predictions, discovering hidden insights, and improving decision-making. Visualization tools, such as line charts, scatter plots, and heatmaps, are essential in spotting trends visually. For example, plotting data points over time can reveal trends like growth, decline, or seasonal variations. Statistical techniques, like moving averages or time series analysis, can help smooth noisy data, making it easier to identify underlying patterns.
