Homonym: Variability (Diversity)
Variability refers to the degree to which data points in a set differ from each other. It is an important concept in statistics, as it helps to understand the spread or dispersion of data. High variability indicates that the data points are widely spread out, while low variability means they are clustered closely together.
In everyday life, variability can be observed in many situations, such as the weather from day to day or the performance of students in a class. Understanding variability allows us to make better predictions and decisions based on the range of possible outcomes.
