Before Change

    similarities.append(source_hash.jaccard(target_hash))

  avg_similarity = sum(similarities) / len(similarities)
  print("average similarity: " + str(avg_similarity))

After Change

  avg_similarity = sum(similarities) / len(similarities)
  sim_std = math.sqrt(
      sum([(x - avg_similarity) ** 2 for x in similarities]) /
      (len(similarities) - 1))

  sim = "average similarity: " + str(avg_similarity) + " (%f)" % (sim_std)
  print(sim)
  output.write(sim + "\n")
