In python, I can do this by using python, as in How do I calculate percentiles with python/numpy?

import numpy as np
a = np.array([1,2,3,4,5])
p = np.percentile(a, 50)

I want to know what is the convenient way in 2018 to calculate percentile in Ruby?

That is few lines function, developer can write it by his own in 2018. But you can check descriptive_statistics gem.

require 'descriptive_statistics'
data = [1,2,3,4,5]
data.percentile(50)

  • I've already implemented my own approach, but I always think to put it into some module like numpy would by much better. – ZK Zhao Mar 12 '18 at 12:53
