Average Calculator

Mean is the sum of all values divided by count (average). Median is the middle value when sorted. Mode is the most frequently occurring value. Each measures central tendency differently.

Use median when data has outliers or is skewed. For example, median income is more representative than mean income because a few very high earners can skew the average.

Weighted average multiplies each value by its weight, sums the products, and divides by sum of weights. It's used when some values are more important than others (like CGPA calculation).
