Introduction

Data Science is one of the flourishing industry. Countries and companies around the world are continuously experiencing a rush in the amount of data collected. They are determined to hire experts who can work on their data and improve their lives.

Such experts are known by many names. Most popular being, ‘Data Scientist’. Among others include Data Engineers, Data Architects, Statisticians etc. But, how many of us are clear about the difference in these roles and designations?

As I’ve experienced, people are confused between a Data Scientist, Data Engineer and Statistics. Some end up concluding, all these people do the same job, its just their names are different. I got astonished at hearing such answers. With these thoughts in mind, I decided to create a simple infographic to help you understand the job roles of a Data Scientist vs Data Engineer vs Statistician. This will help you to decide the best job role for you in coming future.

Very good article! I fall more into the "data engineer' category, but it is very important to know about the other categories as they are related.

Hi manish, Good article. Just curious to know, apart from above, is MIS (excel-access data preparators/reporters) field diminishing. What is the future of MIS? thanks

Hi Deepak, In simple words, MIS profile is like an All-Rounder in cricket. MIS Executive broadly does two things:Data Handling (at lowers scale) and Data Analysis. Future of MIS Executive depends on which path he/she chooses from the two defined above. If he/she chooses data analysis, then there is incredible world of data science and machine learning ahead. If one chooses Data Handling, then is bright future ahead in gigantic world of Big Data Analytics. Both ways, the future is promising and safe. Regards Manish
