This is an NPM module providing a collection of statistical methods including mean, mode, median, range, variance, standard deviation, sum and product.

To use it, simple install via NPM and include it in your project file.

```js

var sm = require('statistical-methods');

```

Then, use the following functions to perform statistical analysis on your data.

```js

var arr = [ 8, 9, 10, 10, 10, 11, 11, 11, 12, 13];

console.log(sm.mean(arr)); // 10.5

console.log(sm.median(arr)); // 10.5

console.log(sm.mode(arr)); // [10, 11]

console.log(sm.min(arr)); // 8

console.log(sm.max(arr)); // 13

console.log(sm.range(arr)); // 5

console.log(sm.variance(arr)); // 2.0555555555555554,

console.log(sm.stddev(arr)); // 1.4337208778404378,

console.log(sm.sum(arr)); // 105

console.log(sm.prod(arr)); // 14949792000

```

The expected data format for all functions is an array of numbers (integers or floats).
