Definition
A weighted average is an average that takes into account the relative importance of each value, calculated by multiplying each value by its weight and summing the results.
Description
The weighted average 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 average provides a more accurate representation of data by considering the relative importance of each value.
In math education, the weighted average is introduced to help students understand how different factors can influence an average. Teachers use weighted averages to explain concepts of proportionality and significance, emphasizing their importance in real-world applications. Students often calculate weighted averages as part of exercises on data analysis, enhancing their understanding of complex averaging techniques.
