Course contents:

Introduction to elementary data analysis based on modern tools 

- Datatypes and data-uploading from various file formats.

- Visualization and explorative analysis for identification of structure and trends (histograms, scatterplots, box-plots etc.).

- Some simple statistics (mean, median, variance etc). 

- Correlation and covariance (of variables and matrix data).

- Crosstables.

- Elementary normal distribution theory, normalizing transformations and testing of normality.

- Geometric distributions, binomial distributions, Poisson-distributions.

- Inference (parametrical and non-parametrical for investigation of one and two samples) and simple analysis of variance.

- Least squares modelling (linear and polynomial fit).

- Logistic regression (classification with two groups).

- Smoothing of time-dependent data.

- Cluster analysis (k-means).

Learning outcome:

Skills and insight into basic data analysis techniques based on modern data collection. The student will learn to choose appropriate methods for

1) Explorative data analysis (plotting/visualisation and descriptive statistics),

2) Visualisation,

3) Inference,

4) Modelling and prediction with continous and categorical responses (regression and classification) and validation of predictive models.

5) Introduction to cluster analysis and smoothing of time series data.

Type of course:
Lectures: 2 hours per week. Lectures/exercises: 2 hours per week. Exercises: 2 hours per week.
Examiner:
The external and internal examiner jointly prepare the exam questions and the correction manual. The external examiner reviews the internal examiner's examination results by correcting a random sample of candidate's exams as a calibration according to the Department's guidelines for examination markings.
