This module calculate Min, Max, Avg, % of standard deviation, median, quartiles, range and histogram from an array
npm install arraystatThis module calculate Min, Max, Avg, % of standard deviation, median, quartiles, range and histogram from an array
- sum : the sum of all the values of the array
- nb : the number of values in the array
- avg : the average value (sum/nb)
- stddev : standard deviation in percent ( (value - avg) / nb / avg )
- min : the minimum value in the array
- q1 : the 1st quartile
- median : the median
- q3 : the last quartile
- max : the maximum value in the array
- range : the range of the array (max - min)
- histogram : a repartition of all the values of the array in 5 buckets
Go into a node project and type the following :
$> npm install arraystat
import arraystat from 'arraystat';
console.log(arraystat([1,2,3,4,5]));
/*
{
sum: 15,
nb: 5,
avg: 3,
stddev: 0.4, // => 40 %
min: 1,
q1: 2,
median: 3,
q3: 4,
max: 5,
range: 4,
histogram:
[
{ min: 1, max: 1.8, nb: 1 },
{ min: 1.8, max: 2.6, nb: 1 },
{ min: 2.6, max: 3.4, nb: 1 },
{ min: 3.4, max: 4.2, nb: 1 },
{ min: 4.2, max: 5, nb: 1 }
]
}
