What is Data Science?

Learning about the world from data using computation

• Exploration
• Identifying patterns in data
• Uses visualizations
• Inference
• Using data to draw reliable conclusions about the world
• Uses statistics
• Prediction
• Making informed guesses about unobserved data
• Uses machine learning

Connector Courses

• Data science is driven by applications
• Every data-driven subject brings new challenges
• Most connectors are small, independent courses taught by Berkeley faculty who are excited to share their expertise
• Three connectors (CS 88, Stat 88, Stat 89A) go deeper into the theory and computation
