Overview

🎯

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.

💼

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.

Previous Year Questions

Unit 12023 · 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 · 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 (α=0.05).

Unit 42022 · End Semester6 marks

Explain the structure of a research paper (IMRaD). What are the key components of an abstract? Compare IEEE and APA citation styles.

Exam Strategy

📖

Research process steps

Problem formulation → Literature review → Hypothesis → Methodology → Data collection → Analysis → Conclusion. Know this flow. Explain with examples.

📊

Statistics calculations

Mean, median, mode, standard deviation, t-test — practice 3-4 problems. Know when to use t-test vs ANOVA. p-value < 0.05 = significant.

✍️

Paper structure

IMRaD format (Introduction, Methods, Results, Discussion). Abstract writing (200 words, objective, method, results). Citation styles (IEEE vs APA). Always asked.
