Lecture 4. WEIGHTED MEAN
Caption: The weighted mean is a statistical measure that assigns different weights to values in a data set based on their relative importance. It is calculated by multiplying each value by its corresponding weight, adding up the products, and dividing by the sum of the weights. The weighted mean is useful when some values in the data set are more important than others.

Keywords: weighted mean, statistical measure, data set, relative importance, weights, arithmetic mean, formula, importance, survey, financial analysis, assets, investments.
