Overview
๐ŸŽฏ
Why it matters
Research methodology is essential for pursuing higher studies (M.Tech, PhD), writing technical papers, conducting experiments, and building a career in academia or R&D. Understanding how to formulate problems, design experiments, and present findings is critical.
๐Ÿ’ผ
Placement relevance
Required for PhD admissions. Research internships at IITs, IISc, Microsoft Research. Publication record boosts profile. Essential for R&D roles at core companies. Less direct placement impact but crucial for academic path.

Unit 12023 ยท End Semester10 marks
Define research problem. How do you formulate a research problem in computer science? Give an example from AI/ML domain. Explain the importance of literature review.
Unit 32023 ยท End Semester8 marks
Given dataset: [23, 45, 12, 67, 34, 56, 89]. Calculate mean, median, mode, standard deviation. Perform a t-test to check if mean differs from 50 (ฮฑ=0.05).
