Why is data science a good career to explore?
Advancements in technology helped data science evolve from cleaning datasets and applying statistical methods to a field that encompasses data analysis, predictive analytics, data mining, business intelligence, machine learning, deep learning, and so much more. Now, there still might be some who think that data science is just a trend and the hype around it will eventually go away. Of course, nothing could be farther from reality. The truth is, data science is just gaining speed as all businesses (and government organizations) use enormous volumes of data to improve what they do and how they do it. But what makes data science the magic ingredient for success? Here are two tangible examples.
The Brazilian Grand Prix 2012. Red Bull’s Sebastian Vettel suffers the worst possible start, his car spinning out of control and losing its front wing on his opening lap. Vettel suddenly drops down to last. All seems doomed for the champion. However, the German somehow manages to recover and finish sixth, which grants him just enough points to snatch the world title for the third year in a row in the most dramatic fashion. Fierce driving or luck?
Nope. That’s data science.
Turns out, by the time Vettel made it to his 10-th lap pit stop, a team of brilliant data engineers had already used modeled data to run simulations. Thus, they were able to analyze what adjustments were necessary to keep Sebastian’s Renault going for the remaining 70 laps. What a huge victory fueled by data!
Caesars Entertainment Corporation was the fourth-largest gaming company in the world in 2013, with annual revenues of $8.6 billion. Based in Nevada, US, it runs more than 50 hotels and casinos around the world, some of them at the most lucrative locations in Las Vegas.
But do you know what Caesar’s most valuable asset is?
It’s their database, giving indispensable insight into 45 million hotel and casino customers’ behavior and spending patterns.
The corporation used 17 years of gathering information to build “an automated, targeted marketing strategy for every individual customer, using data to understand who they are, and then predictive modeling to assess the best way to incentivize them to spend money.” (Marr, 2016)
What does this mean in practice?
Well, if you’re a client with a high lifetime value that happens to have lost all their luck, dignity, and money at the Blackjack table, you’ll most certainly be approached by a staff member. They’ll immediately lift your spirits by serving you your favorite drink. Or they’ll hand you free tickets to an evening entertainment program, and even offer you other free perks they know your heart desires. That way, Ceasar makes sure you’re happy and satisfied and keeps you coming back for more.
