Forecast refers to the process of predicting future events or trends based on current and historical data. In various contexts, such as meteorology, economics, or business, forecasting involves using statistical methods and modeling techniques to estimate outcomes. For example, a weather forecast predicts atmospheric conditions like temperature and precipitation, while a financial forecast estimates future revenue and expenses for a business. The accuracy of a forecast can depend on the quality of the data, the chosen method of analysis, and the inherent variability of the factors being predicted. Overall, forecasting aims to provide insights that help in decision-making and planning for the future.
