What is average?
The average or arithmetic mean is the sum of all values divided by the number of values. It's a measure of central tendency that indicates the typical value of a data set.
Types of averages
The arithmetic mean treats all values equally. The weighted mean assigns different importances (weights) to each value. Other averages include the geometric and harmonic mean.
When to use each type
Use simple mean for homogeneous data. Use weighted when some values are more important (e.g., grades with different credits). Median is better when there are outliers.
