About Data Science Jobs

The history of data science dates back to 1962 when the US mathematician John W. Tukey wrote his book The Future of Data Analysis. There, he pointed out the shifting interest from statistics to data analysis as a more scientific approach.

Ever since the official field’s establishment over 20 years ago, it has captured the attention of almost all industries. The purpose of data science jobs is to provide insights to businesses and organizations regarding stakeholders’ data to make better and more informed decisions.

The modern definition of data science is a multidisciplinary field that combines the work of mathematics, statistics, computer science, and communication through storytelling. It’s essential to have the skills required for all these fields to qualify for jobs in data science.

What Do Data Scientists Do?

Data science covers quite a range of disciplines, which may cause confusion about the exact tasks and responsibilities of the profession. Most people can’t tell how a data scientist is different from a statistician, a mathematician, or a software engineer. So, in the next section, we’ll elaborate on the data scientist job description and daily tasks.

Duties and Responsibilities

A data scientist’s roles tend to be broad, but the following list gives a general idea of their day-to-day activities:
