normally distribute data nd split them into 0-100 buckets

gistfile1.txt

var data =  [2,3,4,5,3,2,3,4,5,6,9,9,100,-100];


var avg = 0;

data.forEach(function(a) {
  avg+= a;
});
avg = avg / data.length;
console.log("avg",avg);

var devs = 0;
data.forEach(function(a) {
  devs += Math.pow(avg-a,2);
});

var standard_deviation = Math.sqrt(devs/(data.length-1));

console.log("std",standard_deviation);

//now put them into buckets of 0-100j
data.forEach(function(a) {
  console.log(a,(100/2)+(100/8)*(a-avg)/standard_deviation);
});
