Variability

Variability refers to the way things differ or change within a certain context. In general knowledge, this can apply to various areas, such as opinions, behavior, data, or outcomes. For instance, if we look at test scores in a classroom, variability shows how much the scores differ among students. High variability means scores are widely spaced apart, while low variability indicates that most scores are similar. Understanding variability helps us grasp the complexity of situations and make informed decisions based on the range of possibilities or experiences present.
