What is an Average?
In mathematics, the "average" most commonly refers to the arithmetic mean. It represents a central value of a finite set of numbers: specifically, the sum of the values divided by the number of values.

While a simple mean treats every number equally, a weighted average gives more importance to some numbers than others. This is common in grading systems where a final exam might be worth 40% of the grade while homework is only 10%.
How to Calculate Mean
Sum up all the numbers in your set, then divide that sum by however many numbers there are. Formula: Average = (xâ + xâ + ... + xâ) / n
