Lecturer: Michael Gratwohl, assistant professor for Energy Finance, University of St. Gallen


  • Interest in and knowledge about statistical methods for biomedical research
  • Practical application in EViews and Excel
  • Preparation, analysis, interpretation, and presentation of data (basics)

Audience: Ph.D. students in biomedicine, 1st/2nd year, basic/moderate knowledge
Date: April 11-15, 2016
Language: English
Preparation: Bring your own data
Schedule: 4 afternoons
Structure: Theory, practical work, discussion

Day 1 Preparation
Realization and descriptive statistics: correlations, moments, structure 
Estimated underlying distribution: probability density and cumulative distribution
Optimization criteria: mathematical arguments and the role of preferences
Goal Master standard descriptive statistics and deduce tender points thereof.

PPT: Descriptive information as the gauge for hypothetical distributions

Day 2 Analysis
Problem statement: formulating the desired result in a testable way
Central limit theorem: the magic of the normally distributed sample means
Hypothesis testing: statement, interpretation, and justification
Goal Formulate your problem statement and understand 'significance'.

PPT: Hypothesis testing as the scientific path for significant results

Day 3 Interpretation
Correlation: causality from content, not statistics
Linear regression: standard ordinary least squares (OLS)
Transformations: necessities and consequences for the error term
Goal Discern correlation and causality and set up a meaningful OLS model.

PPT: Relations between variables as indications for explanations

Day 4 Presentation
Driving your point home: visual support or manipulation?
Graphs: alternatives for distributions, proportions, models, time series, shares
Statistical information: empirical or estimated confidence intervals
Goal Realize the power of framing and depiction to make your point

PPT: Text, tables, and pictures for a convincing message
