About this Course

In these lectures the basic positions of biostatistics are discussed: population, samples, the calculations of the mean, the variance and standard deviation, graphical presentations of distributions. The method of the least squares is explained and also its applications as time series and correlation techniques. The testing of the hypothesis about the mean, the variance and the significance of the correlation dependence are described too. All the themes are submitted by examples with mathematical calculations and explanations of the final results. Tasks for trainings in statistics are added.
