### Tell us what’s happening:

The variance formula might be wrong? I think it should be divided by (n-1) instead of n.

### Your code so far

```
/* file: script.js */
const getVariance = (array) => {
const mean = getMean(array);
const variance = array.reduce((acc, el) => {
const difference = el - mean;
const squared = difference ** 2;
return acc + squared;
}, 0);
}
```
