The is comprised of five sections.

First, designing randomized evaluations,

• where we tackle the question, what is evaluation?
• What is the purpose of evaluation in general?
• And what is the theory behind our evaluation question?

Second, selecting a sample.

Below are the steps I followed to create edx devstack on ubuntu 16.04 running inside virtualbox on Windows 10.

Create virtual box ubuntu instance with atleast 20 Gig so that you do not run into disk full errors.

    sudo apt install git
    sudo apt-get update
    sudo apt install make
    curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
