```
npm install --save atlas-mean
```

## why

Breaking up [atlas-dataset](https://github.com/atlassubbed/atlas-dataset#readme) into standalone functions. This module computes the mean value over an array of numbers:

</p>

## examples

```javascript
const mean = require("atlas-mean")
console.log(mean([1,2,3,4,5,6,7,8,9,10]))
// 5.5
```
