Correct terminology for "normalizing" data (making them add up to 1)

335 Views Asked by At

Let's say I have the data points 2, 2, 8, 10 (sum = 22) and convert them to:

2  -> 2/22  = 0.09
2  -> 2/22  = 0.09
8  -> 8/22  = 0.36
10 -> 10/22 = 0.45

What exactly did I do? Normalize them? Percentalize (sigh...) them? I'm pretty sure I didn't perform a 0-1 normalization (according to the formula found here e http://en.wikipedia.org/wiki/Normalization_(statistics)) since that does not necessarily mean they add up to 1.

What's the correct terminology to use when making a collection of numbers relative to the sum (add up to 1)?
