Tell us what’s happening:
Hello everyone,
Is it correct to make sure that we are at the last index of the array and to get the average:
const getVariance = (array) => {
const mean = getMean(array);
const variance = array.reduce((acc, el) => {
const difference = el - mean
const squared = difference ** 2
acc + squared
squared[array.length -1]
? squared[array.length -1] / array.length
: squared
},0);
return variance;
}
