Measures of central tendency (mean, median, mode, etc.) are some of the first concepts we learn in any basic statistics course. Such concepts are illustrated with several examples, such as: the mean height of the students in the class (or more sensitive information such as age or weight), or the mean/median salary of a company. It is essential to understand these concepts to better understand the world around us. In this post, however, the goal is not to explain neither the concepts, nor why they are important, but to answer the question: what does it have to do with computer science?
