Module B.2: Basic Statistical Concepts

In this module we will introduce at a high level the basic concepts of statistical analysis. We will present different types of exploratory analysis through descriptive statistics, while we will pinpoint on potential problems that can arise from them. In particular, we will discuss the notion of robust statistics by utilizing the example of mean versus median. We will also introduce the concept of statistical testing through specific security-based case-studies. Another possible problem with a novice data analyst is the possible confusion between precision and significance. It is very common numbers with high precision to be treated as more “accurate” and significant as compared to numbers/results with less precision.
