What is Data Science?
As a discipline, Data science involves the collection and study of data – both structured and unstructured – to gain insights and information that can be used by organizations to create effective strategies. By collecting and analyzing data over time, patterns can allow data scientists to identify trends and make suggestions to stakeholders that will help them to find new market opportunities, enhance efficiency, reduce costs, and result in a competitive advantage in their industry.

Why Data Science?
Due to rapid technological advances, especially in areas like mobile advertising, social media, and website personalization, a massive amount of data is being generated daily. These data volumes have resulted in industries having to become data-savvy & adapt to the new landscape – or risk falling behind the competition. Institutions, both public and private, have realized the need for Data Science implementation within their organizations. Universities have responded to this need by introducing data science courses for learners of all backgrounds.
What Does a Data Scientist Do?
Before deciding what the best Data Science course track is to get on, people should make sure they know what data scientists do. In short, they identify problems in existing data analytics and plan to dig deeper into more data to fix them. They do this throughout the entire lifecycle - from choosing the correct datasets to work with, collecting both structured and unstructured data from multiple sources, cleaning and validating datasets, creating and applying algorithms to mine the data, then analyzing and interpreting it, and finally presenting the findings to key stakeholders.
Programming Languages Needed for Data Scientist
One of the most widely used programming language used by data scientists is R. help It’s used by businesses to analyze vast amounts of information quickly and effectively. It is a free, open-source software environment used for statistical computing and visualization, and graphics. It is highly flexible and supports deep learning employed in Data Science. You can learn more about it from the R Project.
Our Data Scientist Master's Program covers core topics such as R, Python, Machine Learning, Tableau, Hadoop, and Spark. Get started on your journey today!
Why Become a Data Scientist?
According to a recent study conducted by Indeed, by January 2019, there had been a 29 percent increase year over year in job postings for data scientists. Since 2013, there has been a 344 percent increase in postings. Between January 2018 and 2019, professionals seeking data science jobs rose by only 14 percent, indicating significant demand for — and lack thereof — for data scientists in the market.
So, why should anyone decide to learn data science? Skilled, certified data scientists are among the highest-paid professionals in the IT industry, with the average salary for a US-based data scientist is $117,345, according to Glassdoor.
