Stanford Stats 200, also known as Introduction to Statistical Inference, is a foundational course in statistics offered by Stanford University. This course provides students with a comprehensive introduction to the concepts and methods of statistical inference, which is a crucial aspect of data analysis in various fields, including medicine, social sciences, and engineering. The course covers topics such as probability theory, sampling distributions, confidence intervals, hypothesis testing, and regression analysis, with a strong emphasis on practical applications and interpretation of results.
Course Overview
Stanford Stats 200 is designed for undergraduate students who have completed introductory courses in statistics and mathematics. The course aims to equip students with the theoretical foundations and practical skills necessary to analyze and interpret data in a statistically sound manner. The course material is divided into several modules, each focusing on a specific aspect of statistical inference. Students learn how to formulate research questions, design studies, collect and analyze data, and draw meaningful conclusions from their findings. The course also emphasizes the importance of critical thinking and communication of results in statistical analysis.
Key Topics and Concepts
Some of the key topics covered in Stanford Stats 200 include:
- Probability theory: axioms of probability, conditional probability, and Bayes’ theorem
- Sampling distributions: central limit theorem, standard error, and confidence intervals
- Hypothesis testing: null and alternative hypotheses, test statistics, and p-values
- Regression analysis: simple and multiple linear regression, regression diagnostics, and model selection
These topics are introduced through a combination of lectures, discussions, and hands-on exercises, allowing students to develop a deep understanding of the underlying concepts and their practical applications.

| Probability Theory | Introduction to probability axioms, conditional probability, and Bayes' theorem |
| Sampling Distributions | Central limit theorem, standard error, and confidence intervals |
| Hypothesis Testing | |
| Regression Analysis | Simple and multiple linear regression, regression diagnostics, and model selection |
Assessments and Evaluation
Student performance in Stanford Stats 200 is evaluated through a combination of homework assignments, quizzes, and a final project. The homework assignments are designed to test students’ understanding of key concepts and their ability to apply statistical techniques to real-world problems. The quizzes assess students’ knowledge of probability theory, sampling distributions, and hypothesis testing, while the final project requires students to design and conduct a statistical analysis on a topic of their choice. The course also includes peer review and feedback components, allowing students to refine their work and develop their communication skills.
Learning Outcomes
Upon completing Stanford Stats 200, students are expected to be able to:
- Formulate research questions and design studies to address them
- Analyze and interpret data using statistical techniques
- Draw meaningful conclusions from data and communicate results effectively
- Apply statistical concepts to real-world problems in various fields
These learning outcomes are achieved through a combination of lectures, discussions, and hands-on exercises, as well as collaborative learning and independent study.
