Biostatistics is an essential skill for every public health researcher because it provides a set of precise methods for extracting meaningful conclusions from data. In this second course of the Biostatistics in Public Health Specialization, you'll learn to evaluate sample variability and apply statistical hypothesis testing methods. Along the way, you'll perform calculations and interpret real-world data from the published scientific literature. Topics include sample statistics, the central limit theorem, confidence intervals, hypothesis testing, and p values.

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 asthma medication and the other about self-administration of injectable contraception. 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 the Summarization and Measurement course, then this scenario will be familiar.

Principales reseñas sobre PRUEBA DE HIPÓTESIS EN EL ÁREA DE LA SALUD PÚBLICA
por JC8 de dic. de 2020
Very good refreshment and well explained. I need to more practical exercises to produce the results. Survival analysis curves are new to me I need to read more
por AB5 de abr. de 2020
Great overview of basic hypothesis testing for means, proportions, and survival curves. Only additional thing that would be nice was a deeper review of the code involved in R.
por AA22 de abr. de 2020
I love the way how the Instructor builds on previous course. very simple and conceptual explanation of the concepts.
por VR30 de dic. de 2020
I was able to review all of the concepts I learned previously in biostatistics. This is an excellent refresher course. Professor McGready is quite articulate and knowledgeable.
