Arithmetic average
The arithmetic average is the sum of values divided by the number of values. It is useful when all data points have equal importance.
Weighted average
The weighted average multiplies each value by its weight before dividing by the total weight. Use this when values contribute differently, such as exam grades with different percentages.
Input format
Enter values separated by commas or line breaks. In weighted mode, provide one weight for each value in the same order.
