Standard Deviation Function

Last review: March 2024


Calculate a standard deviation from numbers inserted to Text Inputs in a Document or Bundled Documents.


  1. Create the Template tag StandardDeviation and attach this tag to all Text Inputs in your Template that should be calculated.
  2. Create the Template tag GetStandardDeviationValue and attach this tag to the Text Input in your Template where the sum amount should be inserted.
  3. Insert the below-mentioned script to the StandardDeviation tag.

Script Example:

const Tags = LEGITO.documentBuilder.getTagsByName("StandardDeviation");


var finder = LEGITO.documentBuilder.event.createElementFinder();
var modeValues = finder.findElementsByTagsAuto(Tags);


const Results = LEGITO.documentBuilder.getTagsByName("GetStandardDeviationValue");
var resultElement = finder.findElementsByTagsAuto(Results)[0];


let valuesArray = []
for(var i in modeValues) {
if(modeValues[i].getValue() !== null) {
valuesArray.push(parseInt(modeValues[i].getValue(), 10));


const n = valuesArray.length;
const mean = valuesArray.reduce((a,b) => a+b)/n;
const s = Math.sqrt( => Math.pow(x-mean,2)).reduce((a,b) => a+b)/n);
