Table 2.3: Examples of natural experiments using big data sources.
Many big data systems are always-on;
Understanding these characteristics are a necessary first step to learning from big data.
Big data sources do not mean the end of survey research. In fact, it is the opposite.
In fact, people who have worked with big data sources know that they are frequently dirty.
Finally, big data increases our ability to make causal estimates from observational data. .
What these examples share is that they all show that counting big data can be used to test theoretical predictions.
In conclusion, the big data sources of today(and tomorrow) generally have ten characteristics.
Based on the ideas in this chapter,I think that there are three main ways that big data sources will be most valuable for social research:.
In some cases, big data enables you to do this counting relatively directly(as in the case of New York Taxis).
Social scientists call this match construct validity andit is a major challenge with using big data sources for social research(Lazer 2015).
Many other big data sources also have information that is sensitive, which is part of the reason why they are often inaccessible.
This probably seems obvious to researchers accustomed to running experiments,but it is very important for those accustomed to working with big data sources(see chapter 2).
Most big data sources are incomplete, in the sense that they don't have the information that you will want for your research.
A 12-week or 3-month course from Innovative Technology Solutions on Data Science is likely the bestwagered for the individuals who wish to go into the universe of Big Data Analytics.
Unfortunately, many big data systems- especially business systems- are changing all the time, a process that I will call drift.
Further, as I will describe later in the chapter,the behavior captured in big data sources is sometimes impacted by the goals of platform owners, an issue I will call algorithmic confounding.
The growth of always-on, big data systems increases our ability to effectively use two existing methods: natural experiments and matching.
Naturally, this is going to be tricky, but big data greatly improves our ability to make causal estimates in these situations.
Two features of big data sources- their always-on nature and their size- greatly enhances our ability to learn from natural experiments when they occur.
Some researchers believe that big data sources, especially those from online sources, are pristine because they are collected automatically.
Unfortunately, many big data systems- especially business system that create and capture digital traces- are changing all the time, a process that I will call drift.
Given these ten characteristics of big data sources and the inherent limitations of even perfectly observed data, what kind of research strategies are useful?
It is a comprehensive Hadoop Big Data training course designed by industry experts considering current industry job requirements to provide in-depth learning on big data and Hadoop Modules.
