Weighted methods are techniques used to assign different levels of importance to various factors or criteria when making decisions or evaluations. By applying weights, decision-makers can prioritize certain elements over others, allowing for a more nuanced analysis. This approach is commonly used in fields like finance, statistics, and machine learning. In practice, weighted methods often involve creating a scoring system where each criterion is multiplied by its assigned weight. The results are then summed to produce an overall score, helping to identify the best option or outcome. This method enhances decision-making by incorporating varying degrees of significance among the factors considered.
