Data Science has become the backbone of the modern digital economy. As of 2026, the field has evolved to integrate heavily with Generative AI and Large Language Models (LLMs), moving beyond simple statistical analysis.
1. Introduction Course Modules
A standard introductory Data Science course is typically structured into “layers,” moving from foundational math to advanced AI.
- Foundation: Mathematics (Linear Algebra, Calculus) and Probability & Statistics.
- Programming: Python (NumPy, Pandas) or R, and SQL for database management.
- Data Wrangling: Techniques for cleaning raw data, handling missing values, and EDA (Exploratory Data Analysis).
- Visualization: Using tools like Tableau, Power BI, or Python libraries like Seaborn and Matplotlib.
- Machine Learning (ML): Supervised (Regression, Classification) and Unsupervised learning (Clustering).
- Generative AI & LLMs: Basic prompt engineering, RAG (Retrieval-Augmented Generation) pipelines, and working with APIs like OpenAI or Gemini.
2. Career Scope & Salary Packages (2026 Estimates)
