What is Variability in Statistics? Variability, also calledspreadordispersion, tells us how much a dataset is spread out. It can explain how much datasets differ, giving us a numerical way to compare datasets. The four main ways to describe variability in a data set are: range Interquartile ...
Variation is a broader term to describe the amount of difference or change present in a dataset. It can be quantified using the variance, but also the standard deviation or range. Variance is a specific form of variation, while variation is a more general concept that includes any type of ...
