Average Calculator
Calculate arithmetic mean, median, sum, and count from numbers.
Calculated across 7 values • Total Sum: 610
How It Works
The Average Calculator analyzes numeric datasets of any size. Enter numbers separated by commas, spaces, tabs, or newlines to compute standard summary statistics.
It computes the arithmetic mean, statistical median (middle value), total sum, minimum, maximum, count of items, and dataset range.
Formula & Calculation
Arithmetic Mean (Average) Formula
Median Formula
Unlike the mean, the median is an outlier-resistant statistic representing the central tendency.
Step-by-Step Example
Example: Dataset of 5 Numbers (10, 20, 30, 40, 50)
Calculating mean, median, and range:
10 + 20 + 30 + 40 + 50→ 150 total sum150 / 5→ 30.00 (Mean)[10, 20, 30, 40, 50] → 3rd number is 30→ 30.00 (Median)The mean is 30.00, median is 30.00, and data range is 40 (50 − 10).
Assumptions & Edge Cases
- Delimiter Flexibility: Inputs can be separated by commas, spaces, tabs, or line breaks. Trailing commas, leading spaces, and blank lines are ignored.
- Single Observation Datasets: When only one valid number is supplied, the mean, median, minimum, and maximum are all equal to that single number, with a range of 0.
Frequently Asked Questions
When should I use the median instead of the mean?
Use the median when dealing with skewed distributions or datasets containing extreme outliers (such as home prices or personal incomes), because a single extreme value will distort the mean but not the median.
