Purdue University

What you'll study

The Bachelor in Data Science at Purdue emphasises core foundations in mathematics, statistics and computer science alongside applied coursework in data technologies and domain-specific applications. Typical core modules include calculus and linear algebra, probability and mathematical statistics, introductory and advanced programming (often Python and R), data structures and algorithms, and database systems.

• Statistical and mathematical foundations: probability, inferential statistics, regression and experimental design.
• Computational skills: programming, algorithms, software engineering practices, and high-performance computing concepts.
• Data technologies: databases, data warehousing, data wrangling, big-data frameworks, and cloud-based processing.
• Machine learning and analytics: supervised and unsupervised learning, model evaluation, natural language processing and time-series analysis.
• Visualisation and communication: interactive visualisation, storytelling with data and practicum in presenting results to non-technical audiences.
• Ethics and professionalism: data privacy, fairness, reproducibility and legal/ethical considerations for data use.
• Capstone and experiential learning: a substantial project or practicum where students apply methods to real-world datasets, often in collaboration with faculty or industry partners.

Students may also choose electives or a minor to develop domain expertise (for example in engineering, life sciences, business or social sciences) and can pursue specialised coursework in areas such as data engineering, computational science or applied machine learning.

Entry requirements

Admission to Purdue's undergraduate data science programmes is competitive and based on a combination of academic preparation and overall profile. Applicants typically need a high school diploma or equivalent with strong achievement in mathematics. Recommended preparation includes courses in calculus (or precalculus leading into calculus), algebra and a grounding in computer science or programming where available.

• Academic background: strong grades in mathematics; additional science and computing coursework is advantageous.
• Standardised tests and credentials: where required, applicants submit standardised test scores and AP/IB/other examination results; exact requirements vary by admission pathway.
• Supporting materials: personal statements, teacher or counsellor recommendations, and evidence of relevant extracurricular experience (coding projects, competitions, research, internships) strengthen applications.
• International applicants: proof of English language proficiency and documentation of equivalent secondary qualifications are required.

Career prospects

Graduates with a Purdue bachelor’s in data science move into a wide range of technical and analytical roles across industry, government and academia. Common job titles include data scientist, data engineer, machine learning engineer, business/data analyst, and analytics consultant. Employers span technology firms, financial services, healthcare, manufacturing, energy, and public-sector organisations.

The degree also provides a strong foundation for graduate study (master’s or PhD) in data science, computer science, statistics, engineering or related fields. Career services, industry partnerships and co‑op/internship opportunities at Purdue help students secure practical experience and full‑time positions after graduation.
