weighted average
This term is primarily used in statistics, finance, and academia to describe a mean that accounts for the relative importance of different data points. It differs from a simple arithmetic mean by assigning a specific weight to each value, ensuring that more significant factors have a greater impact on the final outcome.
In educational contexts, it is frequently used for grading systems where a final exam might be worth more than a quiz. In finance, it is used to calculate the average cost of a portfolio or the average price of shares bought at different times.
