Biostatistics is the application of statistical reasoning to the life sciences, and it's the key to unlocking the data gathered by researchers and the evidence presented in the scientific public health literature. In this course, we'll focus on the use of simple regression methods to determine the relationship between an outcome of interest and a single predictor via a linear equation. Along the way, you'll be introduced to a variety of methods, and you'll practice interpreting data and performing calculations on real data from published studies. Topics include logistic regression, confidence intervals, p-values, Cox regression, confounding, adjustment, and effect modification.

Course Project
During this module, you get the chance to demonstrate what you've learned by putting yourself in the shoes of biostatistical consultant on two different studies, one about self-administration of injectable contraception and one about medical appointment scheduling in Brazil. The two research teams have asked you to help them interpret previously published results in order to inform the planning of their own studies. If you've already taken other courses in this specialization, then this scenario will be familiar.

來自SIMPLE REGRESSION ANALYSIS IN PUBLIC HEALTH 的熱門評論
由 ZA 提供2020年6月4日
Thank you so much for a beautiful explanation and presentation of topics that a lot of physicians tend struggle with, by making it understandable and logical
由 MC 提供2021年10月31日
It would have been helpful to make regression exercises in a computer program. The acquired knowledge is theoretical and not practical, nonetheless it was a good course in general.
由 MA 提供2021年4月1日
Very exciting course, comparing to the previous courses it is completely new to me. Thanks to Ph.D. MS John McCready and to Johns Hopkins University
由 AB 提供2020年4月17日
Dives in depth into regression coefficients and intercept, how to interpret them, and how to evaluate significance.
關於 Biostatistics in Public Health 專項課程
