What Is Average?
The average (arithmetic mean) is the sum of all values divided by the number of values. It's the most common measure of central tendency.
Formula
Mean = (x₁ + x₂ + ... + xₙ) / nExample
The average of 85, 90, 78, 92, and 88 is (85+90+78+92+88)/5 = 433/5 = 86.6.
Frequently Asked Questions
What's the difference between mean, median, and mode?
Mean is the sum divided by count. Median is the middle value when sorted. Mode is the most frequent value.
When should I use average vs median?
Use the median when data has outliers (like income). Use the average for normally distributed data (like test scores).
