Mastering Introduction to Data Science for BTU 3rd Sem Exams
Introduction to Data Science is a core scoring subject in the 3rd Semester for B.Tech CSE, IT, and specialized branches at Bikaner Technical University (BTU). Having a solid understanding of Data Preprocessing, Machine Learning Basics, and libraries like Pandas and NumPy is crucial for clearing university exams as well as preparing for high-paying data analytics interviews. One of the smartest ways to pass is by thoroughly practicing previous year question papers.
As our platform, WriteByHand.in, happily celebrates its 11-month anniversary of empowering students with free study tools, we have curated a well-organized archive of the last 5 years of Data Science PYQs for BTU students.
Table of Contents
Most Repeated Topics in BTU Data Science Papers
1. Data Preprocessing & Cleaning
Expect direct 10-15 mark questions explaining how to handle missing values, outliers, and data normalization. Exploratory Data Analysis (EDA) steps are frequently asked.
2. Python Libraries (NumPy & Pandas)
Questions frequently ask for short code snippets or theory regarding the characteristics of a Pandas DataFrame versus a NumPy array, including indexing and data manipulation.
3. Machine Learning Basics
Theory based on the difference between Supervised and Unsupervised Learning is a university favorite. Topics like Linear Regression, Decision Trees, and K-Means Clustering also appear often.
4. Data Visualization
Be prepared to differentiate between various plotting techniques using Matplotlib and Seaborn. Scatter plots, histograms, and box plots are very common short notes.
