<h1>Data Science is a Process</h1>
28+
<div class="lead">Benjamin Xie & Greg L. Nelson</div>
29+
30+
<p>
31+
We define data science as an <b>iterative process of augmenting human thinking with computational tools to use data to make decisions in/about the world.</b>
32+
</p>
33+
34+
<p>
35+
Let's decompose that definition:
36+
<ul>
37+
<li>
38+
<i>"iterative process"</i>: While we see data science as a process (explained below), it is very much an iterative one.
39+
We will often find ourselves jumping back to a previous step in the process or jumping "out of order" as the situation demands.
40+
</li>
41+
<li>
42+
<i>"augmenting human thinking with computational tools"</i>: Human thinking and reasoning is at the core of data science.
43+
We want to teach you first and foremost how to think like a data scientist. Computational tools supplement human thinking,
44+
but we reiterate that human thinking is at the core of data science.
45+
</li>
46+
<li>
47+
<i>"make decisions in/about the world"</i>: The purpose of data science is inform decisions.
48+
Because these decisions are very dependent on the contexts they are made in, the contexts data scientists work are very critical.
49+
</li>
50+
</ul>
51+
</p>
52+
53+
<p>
54+
We define the <b>data science process</b> as 5 steps:
55+
<ol>
56+
<li>Identify decision context and data science question(s)</li>
57+
<li>Collect and clean data</li>
58+
<li>Model data</li>
59+
<ol>
60+
<li>Generate explanations and models</li>
61+
<li>Evaluate and interpret explanations and models</li>
62+
</ol>
63+
<li>Make/Inform decisions</li>
64+
<li>Archive work</li>
65+
</ol>
66+
67+
We reiterate that this process is iterative and we may jump backwards or out of order to different steps.
68+
We also reiterate that this entire process exists within specific contexts, so data scientists much be critical of their work at each step.
69+
This means (among other things) considering bias in the data, model, and interpretations and ethical and privacy concerns.
