# Statistics in Medicine

This course may be unavailable.

### Overview

This course aims to provide a firm grounding in the foundations of probability and statistics. Specific topics include:

1. Describing data (types of data, data visualization, descriptive statistics)
2. Statistical inference (probability, probability distributions, sampling theory, hypothesis testing, confidence intervals, pitfalls of p-values)
3. Specific statistical tests (ttest, ANOVA, linear correlation, non-parametric tests, relative risks, Chi-square test, exact tests, linear regression, logistic regression, survival analysis; how to choose the right statistical test)

The course focuses on real examples from the medical literature and popular press. Each week starts with "teasers," such as: Should I be worried about lead in lipstick? Should I play the lottery when the jackpot reaches half-a-billion dollars? Does eating red meat increase my risk of being in a traffic accident? We will work our way back from the news coverage to the original study and then to the underlying data. In the process, participants will learn how to read, interpret, and critically evaluate the statistics in medical studies.

The course also prepares participants to be able to analyze their own data, guiding them on how to choose the correct statistical test and how to avoid common statistical pitfalls. Optional modules cover advanced math topics and basic data analysis in R.

PREREQUISITES

There are no prerequisites for this course.

Participants will need to be familiar with a few basic math tools: summation sign, factorial, natural log, exponential, and the equation of a line; a brief tutorial is available on the course website for participants who need a refresher on these topics.

It's ok. The teacher was ok and did not explain some concepts as thoroughly as others.

Stanford is hiking up the price of this course, so I don't think it is worth it. There are free videos online that can teach you these principles more clearly.

Also, I wish there were more practice questions. There are not enough to reinforce the concepts by practice.

Outstanding class. Kristin Sainani knows statistics, how to teach and loves both. Examples are kept general enough for everyone but close enough to medicine to keep everyone engaged.

Highly recommended class!

Prof. Sainani is the best! You will have to work at it, but the material will really hold you in good stead for future use and advanced classes.

Indeed an excellent course! Too bad that Stanford terminated it before I was able to complete it. I sincerely hope they will put it back online again.
