Definition
The weighted mean is the average of a data set where each value is multiplied by a weight reflecting its importance.
Description
The weighted mean is used when different data points contribute unequally to the final average. It is commonly applied in finance to calculate portfolio returns, in education to compute weighted grades, and in various fields where data points have different levels of significance. The weighted mean provides a more accurate representation of data by considering the relative importance of each value.
In math education, the weighted mean is introduced to help students understand how different factors can influence an average. Teachers use weighted means to explain concepts of proportionality and significance, emphasizing their importance in real-world applications. Students often calculate weighted means as part of exercises on data analysis, enhancing their understanding of complex averaging techniques.
