Find the arithmetic mean, total sum, count, median, minimum, and maximum of any comma-separated or space-delimited numbers.
The average (arithmetic mean) of the 5 numbers is 30 (Total Sum: 150, Median: 30, Range: 10 to 50).

Average (Mean) = Sum ÷ Count = 150 ÷ 5 = 30

An Average Calculator computes the central value (arithmetic mean) of a dataset by dividing the total sum of all values by the number of values.
Mathematical Formula: Average (Mean) = (x1 + x2 + ... + xn) / n = (Σ x) / n, where Σ x is the total sum and n is the total count of numbers.
Statistical Properties: The arithmetic mean balances the sum of positive and negative deviations from the center, serving as a primary benchmark across mathematics, business, and science.
Outlier Sensitivity: Extreme values (outliers) pull the mean in their direction; in heavily skewed datasets, the median may provide a more representative central metric.
How is the arithmetic average calculated?
Add all numbers in the dataset together to get the total sum, then divide that sum by the total count of numbers.
