Understanding statistics is essential to understand research in the social and behavioral sciences. This course introduces the basics of statistics; not just how to calculate them, but also how to evaluate them. In the first part of the course, methods of descriptive statistics are discussed, e.g. what cases and variables are and how measures of central tendency can be computed (mean, median and mode) and dispersion (standard deviation and variance). Next, the assessment of relationships between variables is discussed, and the concepts correlation and regression are introduced. The second part of the course is concerned with the basics of probability: calculating probabilities, probability distributions and sampling distributions. The third part of the course consists of an introduction to methods of inferential statistics. Confidence intervals and significance tests are discussed and learners are trained to calculate and generate these statistics using freely available statistical software.
