The Road to becoming a Data Scientist — Learning Paths Explored
Last updated on February 18, 2016
Data Science 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.
Are you looking to be one?
In this article, we give you the recommended learning path and all that you need to be a skilled data scientist.
Who they are and what they do
The term “data scientist” is an industry recognized designation for a professional with high analytics experience, industry knowledge, and skills.
A data scientist is responsible for extracting insight from structured and unstructured data that have business-impact. Data scientists are typically high-ranking team leads, or have positions higher than that, 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.
Being the hottest job in the IT field, a Data scientists — on an entry level — earn a median base salary of $100,000. Payscale.com says that Data scientists earn $62,833 — $137,870 per year.
There are 3 education options that can be pursued, if you are considering a career as a data scientist:
- Graduate and degree certificates provide networking, internships, and recognized academic qualifications for a resume
- MOOCs and self-guided learning courses cheap or free, targeted and short, allowing you to complete projects in your own time
- Boot camps are faster and more intense than the traditional degrees
The skills that will give you an advantage
Possessing these technical skills will give you 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 and/or SAS languages
- Unstructured data techniques
- Python (most common), C/C++ Java, Perl
- SQL databases and database querying languages
- Big data platforms like Hadoop, Hive & Pig
The business skills that will give you an advantage:
- Analytic problem-solving: Candidates will need to approach challenges of a higher level, employing the right approach to make the maximum use of time and human resources.
- Effective communication: Candidates will have to detail your techniques and discoveries to technical and non-technical audiences in a language they can understand.
- Intellectual curiosity: Candidates will need to explore new territories and find creative and unusual ways to solve problems.
- Industry knowledge: Candidates will have to understand the way their chosen industry functions and how data is collected, analyzed, and utilized.
The road to being a Data Scientist
A person looking to be a rounded senior data scientist can follow the recommended certification path given 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 hence are always well-tested as compared to open source.
The language is easy to learn and provides a simple option for professionals who already have an established knowledge in SQL.
Many businesses simply 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 36.2 percent market share, according to the IDC.
R: With the R certification and training, professionals will be competent in the 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.
Compared to other languages, R still stands as the one that produces a higher salary of $115,531. It is one of the 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 the modules are devised with the central assumption that hardware failures are ordinary and common and should be handled automatically in a 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, there is no data that is too big.
