📊 Average Calculator (Mean, Median, Mode)

How the Average Calculator (Mean, Median, Mode) Works

Type or paste your numbers separated by commas, spaces, semicolons, or new lines — a column copied from a spreadsheet works too. The calculator finds the three common kinds of "average" and a few related statistics:

• Mean — the sum of all values divided by how many there are.
• Median — the middle value once the numbers are sorted (or the mean of the two middle values).
• Mode — the value or values that appear most often.
• Range — the difference between the largest and smallest value.

The median is often a better "typical value" than the mean when a few extreme values (outliers) pull the mean up or down — which is why incomes and house prices are usually reported as medians.

Formula

Mean   = (x₁ + x₂ + … + xₙ) / n
Median = middle value of the sorted list (n odd), or mean of the two middle values (n even)
Mode   = most frequent value(s)
Range  = maximum − minimum

How to Use It

1. Enter or paste your numbers into the box.
2. Results update as you type.
3. Use "Sorted list" to check your data at a glance.

Frequently Asked Questions

What is the difference between mean, median, and mode?

The mean is the arithmetic average (sum ÷ count), the median is the middle value of the sorted data, and the mode is the most frequent value. For 2, 3, 3, 5, 12: mean = 5, median = 3, mode = 3.

When should I use the median instead of the mean?

Use the median when your data has outliers or is skewed — for example incomes, home prices, or response times — because a few extreme values can distort the mean but barely move the median.

Can a data set have more than one mode?

Yes. If two or more values tie for the highest frequency, the data is bimodal or multimodal and all of them are modes. If every value appears exactly once, there is no mode.
