Statistics are everywhere. The probability it will rain today. Trends over time in unemployment rates. The odds that India will win the next cricket world cup. In sports like football, they started out as a bit of fun but have grown into big business. Statistical analysis also has a key role in medicine, not least in the broad and core discipline of public health.

In this specialisation, you’ll take a peek at what medical research is and how – and indeed why – you turn a vague notion into a scientifically testable hypothesis. You’ll learn about key statistical concepts like sampling, uncertainty, variation, missing values and distributions. Then you’ll get your hands dirty with analysing data sets covering some big public health challenges – fruit and vegetable consumption and cancer, risk factors for diabetes, and predictors of death following heart failure hospitalisation – using R, one of the most widely used and versatile free software packages around.

This specialisation consists of four courses – statistical thinking, linear regression, logistic regression and survival analysis – and is part of our upcoming Global Master in Public Health degree, which is due to start in September 2019.

The specialisation can be taken independently of the GMPH and will assume no knowledge of statistics or R software. You just need an interest in medical matters and quantitative data.

What's inside

Four courses

Introduction to Statistics & Data Analysis in Public Health

(0 hours)
Welcome to Introduction to Statistics & Data Analysis in Public Health! This course will teach you the core building blocks of statistical analysis - types of variables, common distributions, hypothesis testing - and enable you to analyze data sets, describe their key features, and formulate and test hypotheses based on means and proportions.

Linear Regression in R for Public Health

(0 hours)
Welcome to Linear Regression in R for Public Health! Public Health has been defined as “the art and science of preventing disease, prolonging life and promoting health through the organized efforts of society”. Knowing what causes disease and what makes it worse are clearly vital parts of this. This course will show you how to create such models from scratch, beginning with introducing you to the concept of correlation and linear regression before walking you through importing and examining your data, and then showing you how to fit models.

Logistic Regression in R for Public Health

(0 hours)
Welcome to Logistic Regression in R for Public Health! Logistic regression is a statistical method used to predict the probability of an event occurring, making it particularly useful for public health professionals. This course will provide you with a hands-on understanding of logistic regression using R, with a focus on interpreting the results in the context of public health. By the end of this course, you will be able to:

Survival Analysis in R for Public Health

(0 hours)
Welcome to Survival Analysis in R for Public Health! This course will teach you how to run survival analysis, using the popular and free software R. You'll learn how to take a data set from scratch, import it into R, run essential descriptive analyses, and progress from Kaplan-Meier plots through to multiple Cox regression.

Learning objectives

  • Recognise the key components of statistical thinking in order to defend the critical role of statistics in modern public health research and practice
  • Describe a given data set from scratch using descriptive statistics and graphical methods as a first step for more advanced analysis using r software
  • Apply appropriate methods in order to formulate and examine statistical associations between variables within a data set in r
  • Interpret the output from your analysis and appraise the role of chance and bias as explanations for your results
