74948 - STATISTICS FOR HEALTHCARE

Conoscenze e abilità da conseguire

At the end of the course the student is provided with the essential concepts of statistics and probability, with the dual objective of illustrating the basic tools for the exploratory analysis of health-related data and introducing the founding elements of econometrics.

Contenuti

By the end of this course, you should be able to: 1. explain why risk and uncertainty are fundamental to research and decision-making in healthcare; 2. explain some of the fundamental concepts of probability theory, the difference between a population and a sample, experiments, observational studies and sampling error; 3. explain the difference between qualitative and quantitative variables and describe the main discrete and continuous random variables that are relevant for classical statistics. Define and be able to interpret the probability mass and density function, measures of central tendency and dispersion, including the expected value, variance and standard
deviation; 4. explain what is meant by making causal inferences, why randomised controlled experiments may permit us to make them, and the challenges of making causal inferences with
observational data sets; 5. explain, and be able to carry out, numerical and graphical analysis of data in a sample
using descriptive statistics; 6. explain what is meant by the sampling distribution of a statistic, confidence intervals,
hypothesis tests, p-values and test statistics. Be able to test and interpret hypotheses for population means and proportions; 7. explain what is meant by simple regression and multiple regression; 8. using software such as Stata or MS Excel, carry out suitable exploratory analyses using numerical, graphical and tabular descriptive methodologies and test hypotheses using
experimental and observational data sets. Be able to interpret the results of such analyses, explain the statistical methodology underlying the results and interpret the results in a manner which may be understood by non-statisticians.
