weighted average
Importance-adjusted calculation result
A weighted average is an average in which some values count more than others.
In a simple average, all items contribute equally; in a weighted average, each item is multiplied by a factor reflecting its importance.
A student's GPA is a weighted average—a grade in a four-credit course affects it more than a grade in a one-credit course.
The index is a weighted average of stock prices, with larger companies counting more.
