A staggering 2.5 quintillion bytes of data enters the virtual sphere every day, according to IBM. Based on a report from DOMO, experts estimate that by 2020 1.7MB of data will be created every second for every person on earth. This extreme influx of data has only appeared over the last two years, effectively drowning data analysts and IT departments across industries in information.
The question confronting all industries right now is how does the public and private sector cope with this over saturation? In order to understand the answer, researchers and professionals alike must understand the background of the problem before coming up with a solution.
So why did this explosion just occur now? After all, the internet has been around since the '80s, despite still being in its nascent stages. It turns out, the answer to why data has exploded the way it has is quite multifaceted and includes a combination of factors.
Deepak Pareek, a technology strategist, offers a succinct overview of why the amount of data has exploded:
While the reasons behind the explosion of data are fascinating, current analysts must qualify what they mean by “big data” and what to do with this vast quantity of data.
The term “big data” refers not to the sheer quantity of data, but rather to how structured and unstructured data interacts with social media analytics, IoT data, and other external sources in order to paint a picture. With the advent of big data, professionals across businesses face a double-edged sword.
The amount of digital information that exists presents a problem, but the true problem often lies in analysts’ ability or inability to deliver cost-effective and successful data analytics.
One of the most infamous failures of “big data” occurred when the Center for Disease Control (CDC) partnered with Google to create the Google Flu Trend (GFT) project. The CDC along with GFT tried to show a correlation between areas with high rates of internet searches about the flu to areas where outbreaks of the flu would be recorded. Unfortunately, Google’s algorithm was constructed without careful enough parameters, and the result was a wildly inaccurate predictive model based on millions and millions of search terms.
Another problem with big data is the fact that data is not infinitely useful, but has a lifespan of relevance. Those who are responsible for storing and saving this data do not necessarily adopt good housekeeping practices when it comes to evaluating data for importance and relevance which can lead to wasted time and resources.
Professionals who can problem solve in order to produce pertinent research findings in a timely way pose an invaluable resource to companies across fields.
From the medical field to Wall Street, data has started driving important decision making. Often, decision makers must first decide if statistical analysis of their data will satisfy the return on investment. Data mining and analysis can end up being extremely expensive and inconclusive if the correct parameters are not established from the beginning.
But more and more industries are accepting or embracing the idea that their decisions should be driven by accurate information about reliably collected data. This increases the pressure on managers and hiring departments to find people with the skills necessary to make data meaningful to the rest of the organization.
Those with graduate degrees, specifically in the area of Statistical Science, Applied Statistics, and Data Analytics, can offer their employers the necessary expertise to expose relevant data and optimize data analytic projects.
The wealth of information in the modern digital age may minimize knowledge gaps, but only if there are people with the ability to interpret the overwhelming nature of the data. With a Ph.D. in Statistics, you will be in a position to help.
The value of people who understand how to collect accurate information based on reliable data increases exponentially as businesses and individuals struggle to make sense of the volume of information available. Those who grasp how to productively utilize big data will be essential for coming innovation on how to work within the acknowledged limitations of big data to glean the best results.
