The term Data Scientist is in vogue right now. Let’s explore Data Science, what key skills make a data scientist and how SAS’ Academy of Data Science may help advance your career.
The term "data science" (originally used interchangeably with "datalogy") has existed for over thirty years and was used initially as a substitute for “computer science” by Peter Naur in 1960.
Data Science (as we know it), is a relatively new and perhaps ever-evolving discipline. Its definitions vary and there is no standard approach towards this role, unlike traditional professions like accountancy and sales. The most common definition is available at Wikipedia which writes about Data Science: “Data science is an interdisciplinary field about processes and systems to extract knowledge or insights from data in various forms, either structured or unstructured, which is a continuation of some of the data analysis fields such as statistics, data mining, and predictive analytics, similar to Knowledge (KDD).”
Some of the spicy definitions exist over the vastness of the internet which includes the one by Malcolm Chisholm: “There’s a joke running around on Twitter that the definition of a data scientist is ‘a data analyst who lives in California’” . There are websites like Big Data Made Simple which compiles more than 10 definitions of Data Science.
Here is an attempt to figure out what key skills makes a data scientist based on the recent discussions in our Education Team in the context of SAS Academy of Data Science. To begin with the data scientist may be defined as “Data scientists (who are partly artists as well) are a new breed of analytical data experts who have the logical, technical and creative skills to solve complex business/industrial problems across domains or specific domains – and the curiosity/tendency to explore and identify problems that need to be solved in cost-effective and time-efficient manner.”
The key skills that we look for in a Data Scientist are:
- Big Data Management Skills which includes managing technologies and techniques responsible for data capture, transfer, storage, and data processing for analytics. The skills encompasses knowledge of Data Management products, Open Source like Hadoop and their integration with each other.
- Analytical Skills which includes ability to analyses the data with speed and accuracy. Typical skills include knowledge of machine learning techniques (supervised and unsupervised), skills in data mining including predictive modelling, pattern recognition, experimentation and optimization.
- Business Visualization Skills includes ability to showcase results to the business audience enabling them to take timely and correct decisions. Typical skills include knowledge of visualization products and domain expertise and skill set to lead analytical modelling results to actionable business insights.
- Communication Skills which includes ability to contextualize and decode a problem and its solution to interested parties of varying backgrounds using common ground, allegory, skillful listening, and storytelling.
The area of big data analytics is not meeting demand – with a supply gap and a dearth of institutes who can provide industry ready work force with specific tool knowledge and skill set. Fortunately, SAS has created the SAS Academy of Data Science which, after years of hard work, is the world’s first Big Data Scientist program.
The SAS Academy of Data Science attempts to provide these skill sets through a comprehensive Data Scientist course. It runs a Big Data Scientist course which is the first of its kind in the world and nurtures the above skill sets in an organized manner. There are two levels (with five international Certifications).
Level 1: SAS Certified Big Data Professional covers SAS Programming, Introductory Statistics, and Data Management and Manipulation, Data Quality, Working with Hadoop, Hive and SAS, and Data Visualization.
Level2: SAS Certified Advance Analytical Professional covers Machine Learning techniques including Predictive Modeling (Neural Nets, Forrest, and SVM etc.), Experimentation, Optimization, Segmentation, Text Analytics, Communication, Deployment and Automation. A person who is able to finish both the levels would get the credential of SAS Certified Data Scientist.
As this world of data science is dynamic and innovative, we promise to deliver the most relevant skill sets to the upcoming breed of data scientists. Learn more about SAS Certification and the SAS Academy of Data Science.
A note on Skill Demand for Data Science:
No wonder there is a lots of demand across the globe. As per Mckinsey, by 2018, the U.S. alone may face a 50 percent to 60 percent gap between supply and requisite demand of deep analytic talent. The Centre for Economic Business Research(Cebr) forecasts that the uptake of big data analytics will create almost 70,000 jobs in the UK and 61,000 new jobs in Ireland, by 2017. This is supported by e-skills, the IT skills development organisation, which puts the figure at 69,000 new jobs for the UK. McKinsey estimates that for every data scientist, organizations will need ten data savvy managers with the skills and understanding to make decisions based on data analysis. Similar trends are available across the countries. In India as per the “TOI Exclusive: 23k jobs for big data analytics in Bengaluru: Report,” job market across India is seeing a 32.2% demand with people having analytics and data science qualifications over and above degrees in IT or business administration or even doctorates. This is six to eight times more than the demand for IT jobs that is 26.4% nationally. As per Accenture Analytics, 2016, Accenture Analytics, more than 90 percent of surveyed (sample included leading Indian and MNC companies across industries) said that they planned to hire more employees with expertise in data science—most within a year.
