Data Scientist job description FAQs


What is the difference between a Data Scientist and a Data Analyst?

Both Data Scientists and Data Analysts require statistical knowledge, an understanding of algorithms, communication skills, and software engineering skills, but there are significant differences between the job responsibilities. Data Analysts work directly with the data, and they focus on using programming languages to dissect data and solve business problems. A Data Scientist focuses on the overall picture of data and understands analysis, modelling, math, statistics, and computer science, allowing them to create visualizations and models to communicate the data findings to teams and stakeholders. Data Scientists also have some business acumen and they understand how data relates to business operations.


What qualities make a good Data Scientist?

Talented Data Scientists should demonstrate a sharp business acumen and an understanding of how raw data translates to data-driven business decisions to improve sales, marketing, product development, or customer experience. Ideal candidates should also have a passion for analyzing data, developing statistical models, and communicating this knowledge to teams and stakeholders. It is also important to have a Data Scientist who can communicate high-level technology concepts in an approachable way for the layperson.


What types of businesses need Data Scientists?

Data Science is a growing field that is necessary to virtually every industry. Data Scientists are needed in the retail and hospitality industries to analyze customer data, in the finance sector for financial insights, and in healthcare for disease modelling, improvement of patient experience, and the implementation of wearable healthcare devices. Other industries, such as construction and transportation, employ Data Scientists to analyze patterns such as material-based expenses, time frames, and traffic routes, among others.
