Data Science is among the hottest jobs of the 21st century. Every company out there is looking for data scientists. Data Science is a multidisciplinary field that uses various tools and techniques to collect & organize raw, structured, or unstructured data. That data is eventually used for decision making and numerous other purposes. 

In short, Data Science is all about:

• Collecting and analyzing raw data.
• Modeling the data using various algorithms.
• Visualizing the data to get a better perspective.
• Understanding the data to make better decisions.

Example:

Let’s suppose, you want to pursue an MBA. Now, you need to make some decisions like, What are the best MBA colleges in the country, What are their fee structures, what is the admission procedure, and finally their cut-offs and entrance exams. 

All these decision factors will act as input data, and after you analyze all these things, you’ll be able to decide the best college for yourself. This analysis of data is called data analysis, which is a vital part of data science.

Why Data Science?

Data Science helps an organization to make better decisions, find gaps and opportunities, find a target audience, and even in recruiting the right talent. On top of it, as everything is backed by data it even helps to reduce business risk. 

Data Science even helps you to predict your customer’s next steps on the basis of historical trends such as his/her browsing history, engagement, & demographics.
