Random selection¶

In [5]:

import random
population = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
sample = random.sample(population, 3)
sample

import random population = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10] sample = random.sample(population, 3) sample

Out[5]:

[6, 8, 2]

Random assignment¶

In [11]:

def flip_coin():
    r = random.random()
    if r < 0.5:
        print("intervention")
    else:
        print("control")

flip_coin()

def flip_coin(): r = random.random() if r < 0.5: print("intervention") else: print("control") flip_coin()
