Stats 200, also known as "Introduction to Statistical Inference," is a popular undergraduate course offered by the Department of Statistics at Stanford University. The course is designed to introduce students to the fundamental concepts of statistical inference, including probability, statistical models, and data analysis. In this course, students learn how to extract insights and meaning from data, which is a crucial skill in various fields, including business, medicine, social sciences, and engineering.
Course Objectives and Outline
The primary objective of Stats 200 is to provide students with a comprehensive understanding of statistical inference, including the principles of probability, hypothesis testing, confidence intervals, and regression analysis. The course covers a range of topics, including:
- Probability Theory: Introduction to probability concepts, including random variables, probability distributions, and Bayes' theorem.
- Statistical Models: Linear regression, logistic regression, and generalized linear models.
- Data Analysis: Data visualization, exploratory data analysis, and statistical computing using software such as R or Python.
- Hypothesis Testing: Introduction to hypothesis testing, including t-tests, ANOVA, and non-parametric tests.
- Confidence Intervals: Construction of confidence intervals for population means and proportions.
Course Structure and Requirements
Stats 200 is typically offered during the winter quarter at Stanford University. The course consists of lectures, discussions, and lab sessions, where students work on assignments and projects to apply statistical concepts to real-world problems. Students are expected to have a basic understanding of calculus and linear algebra, as well as familiarity with statistical software such as R or Python.
The course requirements include:
- Weekly assignments and quizzes (40% of the final grade)
- Midterm and final exams (30% of the final grade)
- Group project and presentation (30% of the final grade)
