+The **weighted mean** is an average that gives different data points varying levels of importance. Unlike a simple [Arithmetic Mean](/wiki/Arithmetic_Mean), it assigns a specific [Weight](/wiki/Weight) to each observation, allowing some values to contribute more to the final sum than others. This method is crucial when data points have unequal significance or reliability.
