## Inputs

- Numbers

## Results

- Average (mean)
- Count
- Sum
- Median
- Minimum
- Maximum

## Formula

```
Mean = sum of values ÷ number of values
```

## Explanation

The average, or arithmetic mean, summarises a set of numbers with a single typical value.

### How to use the Average Calculator

- **Numbers**

Results update as you type, and every field accepts the units shown in its menu.

### How it works

Add all values and divide by how many there are. The median is the middle value once sorted.

### What each result means

- **Average (mean)** = [Average (mean)]([Numbers])
- **Count** = count([Numbers])
- **Sum** = sum([Numbers])
- **Median** = median([Numbers])
- **Minimum** = min([Numbers])
- **Maximum** = max([Numbers])

## Worked example

Inputs — Numbers: 12, 15, 9, 21, 18, 15.

Results — **Average (mean) = 15**; Count = 6; Sum = 90; Median = 15; Minimum = 9; Maximum = 21.

## Key terms

- **Mean**: Sum divided by count.
- **Median**: Middle value of sorted data.

## FAQ

**What formula does the Average Calculator use?**
