Averages, Variance, and Making Sense of Data

Numbers are just numbers until you make sense of them. Openmadness helps you understand your data through built-in statistics.

Example: Sum

Let's start with getting the sum of all your numbers. It's as straightforward as calling .sum():

import { omArray } from 'openmadness';

const numbers = omArray([10, 20, 30, 40]);
const totalSum = numbers.sum();
console.log(totalSum); // ➝ 100

Example: Mean (Average)

The mean is simply the average of your numbers. It gives you a single value that represents the "center" of your data. To find the mean, you use .mean():

const sample = omArray([10, 20, 30]);
console.log(sample.mean()); // ➝ 20

Example: Max and Min Sometimes you need to find the highest or lowest value in your data. Openmadness provides .max() and .min() for this purpose:

const scores = omArray([85, 92, 78, 95, 88]);
const highestScore = scores.max();
const lowestScore = scores.min();

console.log(`Highest score: ${highestScore}`); // ➝ Highest score: 95
console.log(`Lowest score: ${lowestScore}`);   // ➝ Lowest score: 78

These operations help you quickly grasp the essence of your numerical data, whether you're looking for totals, averages, or the extremes.
