It’s true: The role of a data scientist is one of the sexiest jobs of the century! The demand for data scientists is high, and the number of opportunities for certified data scientists is increasing. Every day, companies are looking out for more and more skilled data scientists, and studies show that there is expected to be a continued shortfall in qualified candidates to fill the roles.
Are you looking forward to becoming a Data Scientist?
In this article, we give you the recommended learning path and all that you need to know to be a skilled data scientist. You can also check out our Data Science Bootcamp to help you get started.
Who is a Data Scientist and What Do They Do?
The term “data scientist” is an industry-recognized designation for a professional with deep analytics experience, industry knowledge, and skills.
A data scientist is responsible for extracting insight from structured and unstructured data that have potential business impact. Data scientists are typically high-ranking team leads or have even higher positions in an analytics organization. With every industry and function now embracing analytics, having data scientists in an organization has become a necessity. Analytics now governs everything from HR and marketing to sales and supply chain.
Data Scientist Salary Prospects
According to Payscale, data scientists earn $62,288 - $137,002 per year, with a median salary of $91,168.
Qualifications of a Data Scientist
There are three education options that you can pursue if you are considering a career as a data scientist:
- Graduate degrees and certifications provide networking, internships, and recognized academic qualifications for a resume.
- MOOCs and self-guided learning courses, both cheap and free, targeted and short, allow you to complete projects on your own time.
- Boot camps are faster and more intense than traditional degrees.
Data Scientist Skills That Will Give You an Advantage
Possessing these technical skills will provide you with an edge over your peers:
- Statistics (e.g., hypothesis testing and summary statistics)
- Math (e.g., linear algebra, calculus, and probability)
- Machine learning tools and techniques (e.g., k-nearest neighbors, random forests, ensemble methods, etc.)
- Data mining
- Software engineering skills (e.g., distributed computing, algorithms and data structures)
- Data visualization (e.g., ggplot and d3.js) and reporting techniques
- Data cleaning and munging
- R or SAS languages
- Unstructured data techniques
- Python (most common), C/C++ Java, Perl

Data Scientist Learning Path
A person looking to be a well-rounded senior data scientist can follow the recommended learning path shown below.
SAS
SAS is a computer programming language that is used for statistical analysis. It stands as the undisputed market leader in the commercial analytics space.
SAS updates are developed in a controlled environment and are thus always well tested compared to open source. The language is easy to learn and provides a simple option for professionals who already have an established knowledge of SQL.
Many businesses distrust freeware and don't like the idea of not having a software provider verify the efficacy of their application usage. Then there is the matter of market opinion – SAS is leading the advanced analytics segment with a 31.6 percent market share, according to IDC.
R
With the R certification and training, professionals will be competent in R programming language concepts such as data visualizations, exploration, and statistical concepts like linear and logistic regression, cluster analysis, and forecasting.
R is open-source, has a vibrant community, has libraries for extensive analytics and visualization, has a steep learning curve, and integrates with big data and Hadoop. And compared to other languages, R still stands as the one that produces a higher salary of $115,531. It is one of the most in-demand skills.
Data scientists and statisticians around the world use this programming language to solve some of their most challenging problems in fields that range from computational biology to quantitative marketing.
Since complex data is represented through charts and graphs, the language has become an essential part of the data analysis process.
Hadoop
An open-source framework, Hadoop is used for distributed processing and distributed storage of large data sets.
Hadoop is written in Java; all of the modules are devised with the central assumption that hardware failures are ordinary and common and should be handled automatically by the software.
Hadoop has opened new doors for data scientists to store and process data. Instead of depending on proprietary hardware and other systems to process and store data, Hadoop allows parallel distributed processing of massive amounts of data across industry-standard servers that will process and store data. With Hadoop, no data is too big.
