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). Smoothing of time-dependent data. Correlation and covariance (of variables and matrix data). Elementary normal distribution theory, normalizing transformations and testing of normality. Hypotesis testing (parametrical and non-parametrical for investigation of one and two samples) and simpel analysis of variance. Least squares modelling (linear and polynomial fit). Crosstables,  Cluster analysis (k-means). Logistic regression (classification with two groups).
