Words like Data Science and Big Data have become a buzzword today but there is very less clarity related to these terms. This article will focus on the actual meaning of data science, skills required, payscale ,the downsides of the profession and application of data science in Actuarial Science.


Data Science is a multidisciplinary field which involves techniques, algorithms and methods from the fields of mathematics, statistics and computer science, used to analyze structured and unstructured data for explanatory and predictive purposes. A very basic practical example of application of data science may be a shopping website recommending its customers products based on their purchase history.

Many a times it is used interchangeably with data analyses and business intelligence. However, in its true sense it is more predictive than explanatory. It analyses patterns in the data sets to predict future values rather than explaining and making reports out of data.

Downsides of the Profession

Many a times managers hire data scientists with a lack of clarity of purpose and goals.As a data scientist, you need the whole picture. You need to know what your goal is because otherwise you can’t expect to achieve it. Unfortunately, people often narrow that goal with their own theories before presenting it to you.They tend to overestimate (give them ultimate answers to questions) or underestimate (expect making reports and analyses). Data scientist also complain of not being the descision maker. Data science provides suggestions, advices. Usually it’s not decision making role. And many data scientists get frustrated when decision makers follow their instincts ignoring facts.
