Everyone seems to be in love with data science nowadays. Whether at work, park, or grocery store, the hottest topic of discussion is always data scientist.
You know why? Because Harvard calls it the sexiest job of the 21st century! In this article, we will provide data science’s definition and discuss the job responsibilities of data scientists. So if you are intrigued by this amazing field, you will find plenty of useful information here. know more about Data Science Course in Pune
Let’s start exploring.
What is data science?
Data science is the study of various mining tools, algorithms, and AI principles. It focuses on analyzing raw data, also known as big data, and making predictions from that data through machine learning.
Now, you might be thinking that statisticians have been doing the same for years, so what separates them from data scientists. The answer is that statisticians only explain what is going on by processing past trends. On the other hand, big data experts not only do the explanatory part but also make predictions after processing given sets of data.
Below, we’ll discuss in detail the key skills of a data scientist.
What are the key skills of data scientists?
To do the job aptly, data scientists must have strong programming skills. Also, they should possess a deep understanding of statistics, probabilities, and mathematics. Having these skills and knowledge enables data scientists to implement correct solutions all the time.
Here is what big data experts normally do to solve certain problems:
Predictive Analytics
Data scientists develop models using predictive casual analytics to forecast possible future events for different industries and sectors.
This practice is widely used in the retail industry and Amazon is a big example of it. For instance, if you sell on Amazon, connecting with reliable buyers will be a top priority for you.
Using predictive casual analytics, you can build a model that will show you the purchase history of the customer to see if they will return the product or not.
The purpose of this model is to reduce returns and connect you with only genuine buyers.

Prescriptive Analytics
Prescriptive analytics enable data scientist to build intelligent models capable of making their own decisions. The primary focus of prescriptive analytics is on offering advice. Therefore, data scientists use this expertise for suggesting a range of possible actions and their effects.
Google’s self-driving cars are a great example of it. These cars continuously gather data to train themselves and be more intelligent. This allows them to pick the right path, turns, and the time to increase or reduce their speed.
Making Predictions Through Machine Learning
Machine learning is arguably the most important skill for a data scientist. This is because it enables you to train the models that predict future trends.
Another term for machine learning is supervised learning as the machines are trained according to the given data. For example, you can build a fraud detection machine by training your model around the historical record of false purchases. Visit here for more details Data Science Course in Chennai
