Projections, or forecasts, are estimates about future events based on current data and trends. They are commonly used in various fields, such as economics, weather, and business, to predict outcomes like sales, market growth, or climate conditions. By analyzing historical data, experts can create models that help visualize potential future scenarios. These forecasts can guide decision-making and planning. For instance, a company might use sales projections to determine how much inventory to produce, while meteorologists rely on weather forecasts to inform the public about upcoming conditions. Accurate projections can significantly impact strategies and resource allocation in many sectors.
