Calculate the average (mean), median and sum of a list of numbers. Paste your numbers separated by commas, spaces or line breaks.
The average (also called the arithmetic mean) is found by summing all the numbers and dividing by the count:
Median is the number that falls in the middle of the list when the numbers are sorted in ascending order. If the count is even, the median is the average of the two middle numbers. Median is useful because, unlike the average, it isn't heavily affected by extreme individual values (outliers).
The average takes into account the value of every number, while the median only looks at which number is in the middle. If your dataset has a few very high or low numbers, the average can be "skewed" more than the median.
You can use line breaks, commas, semicolons or spaces — the calculator interprets all of these as separators between numbers.
