Frequently Asked Questions

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

The Data Analyst focuses on examining historical data to answer current business questions and design actionable dashboards. On the other hand, a Data Scientist uses advanced statistics, Machine Learning algorithms, and predictive models to forecast future trends and automate complex decision-making processes using both structured and unstructured data.

Is coding skills mandatory to work as a Data Analyst?

It is not strictly mandatory for entry-level roles, where proficiency in SQL and BI tools (like Power BI or Tableau) is usually sufficient. However, to transition into mid-level and senior positions, knowing a programming language like Python or R becomes indispensable for automating workflows and scaling raw data manipulation.
