An efficient and effective one-day refresher on the fundamental tools in statistics. This course covers the two main divisions of statistics: descriptive and inferential statistics.
First, the course covers descriptive statistics: the different types of variables, variability, distributions and the characterization of distributions through well-known statistics such as the mean and standard deviation as well as other less known statistics such as quartiles.
Inferential statistics, also known as statistical testing, is broached next: hypothesis testing, one-sided versus two-sided tests, p-values, risks, significance levels, and confidence intervals.
