Has it ever crossed your mind how the content you see when you hop online is made just as you want it? How do you think social media platforms, such as Instagram, and YouTube, know what kind of stuff you would love to see? Have you ever wondered how these services know what music you want to listen to before you even know it? The answer is simple – data science! But, don’t worry – it’s not as complicated as it sounds.
Data science is a field that combines statistics, mathematics and computer science to understand and analyze data. It’s like being a detective, but for data! Data scientists are like these cool detectives who find patterns and connections in big amounts of information to help companies make decisions. You can see their work in action when, for example, Netflix suggests a movie they think you’ll like based on what you’ve watched before. Or, when your mobile device suggests a word before you’ve even finished typing it. That’s data science at play!
Sometimes, data can be really messy. Imagine your room after you’ve had a sleepover with friends. There are toys, clothes, and food everywhere, right? Now, imagine having to clean all that up but with a blindfold on. That’s how data scientists can feel when they first approach data; it can be messy, noisy, and confusing. But just like you finally manage to clean up your room, data scientists clean up and organize data to make it understandable. This neat process is called ‘data wrangling’ or ‘data munging.’
After cleaning the data, data scientists team up with tech wizards, known as machine learning engineers. These engineers use this clean data to train computers (through a process called ‘machine learning’) to do things like predict what kind of dress you would like to buy next, or maybe, what type of song you’ll want to download.
In short, data science is magic! Data scientists are magicians who use their mathematics and computer science skills to make sense of immense amounts of data for companies to make better decisions. As a result, consumers –like you and me– end up with songs, films, and products that we love. So, the next time Netflix suggests a film you end up enjoying, remember to thank the magicians behind the curtain- the data scientists!
So, if you’re good at problem-solving and you love puzzles, maybe you could consider a future in data science. It’s the future, and it’s entertaining, and who knows, maybe one day you’ll be the magician who suggests the next big hit on Netflix!
