A forecast, or prediction, is an estimate about what will happen in the future based on current data and trends. It is commonly used in various fields, such as meteorology for weather predictions, economics for market trends, and business for sales projections. Forecasts help individuals and organizations make informed decisions by anticipating future events. To create a forecast, analysts often use statistical methods and historical data to identify patterns. For example, a weather forecast might analyze past temperature records to predict future weather conditions. While forecasts can provide valuable insights, they are not always accurate, as unforeseen factors can influence outcomes.
