Angaben zur Abhaltung
The lecture will give an introduction into the basic techniques for the analysis of experimental data. It will cover among other things the following topics:

- The scientific method
- The concept of probability and its interpretations
- Bayes' theorem
- Random variables
- Probability distributions and their moments
- Important distributions: binomial, multinomial, Poisson and Gaussian distribution
- Multivariate distributions
- Marginal and conditional probability distributions
- Covariance and correlation coefficient
- Functions of (multiple) random variables
- Central limit theorem
- Gaussian uncertainty propagation for n-dimensional functions and covariance matrix
- Statistical and systematic uncertainties
- Parameter estimation using the method of least squares
- Estimating the goodness of fit
- Parameter estimation using the (extended) maximum-likelihood method
- Relation between least-squares and maximum-likelihood method
- Estimating the significance of a signal
There are no preconditions in addition to the requirements for the Master’s program in physics.
After successful completion of this module, students are able to

- understand and apply fundamental statistical concepts
- understand and apply basic data-analysis techniques to suitable data
- apply first-order uncertainty propagation in the most general case
- estimate and correctly interpret statistical and systematic uncertainties
- estimate model parameters by performing fits to (multi-dimensional) data
- estimate the statistical significance of signals in the presence of background
- (when attending the tutorials) develop tools for moderately complex data-analysis tasks using the Python programming language

class lecture
The goal of the lecture is to provide a solid theoretical background. To this end, methods and concepts will be derived, where possible, from first principles.

In the tutorials, the concepts that are explained in the lecture will be applied to concrete examples. In small groups of students, short Python programs will be developed. The examples will be mostly from particle physics. However, the tutorials will focus mainly on the statistical aspects of the problems and are prepared such that they do not require deeper particle-physics preknowledge.
