Function deviation

ArrayUtils

Calculates the standard deviation of an array of numbers. The standard deviation measures the amount of variation or dispersion in a set of values. It indicates how much individual values in the array differ from the average (mean) value. A higher standard deviation suggests greater variability, while a lower value indicates less variability.

Example

const numbers = [2, 4, 4, 4, 5, 5, 7, 9];
const standardDeviationValue = standardDeviationArray(numbers);
console.log(standardDeviationValue); // Output: 2
