👉 "Variability" is a broad concept that refers to differences or variations in quality, structure, or behavior between different groups of objects or individuals. It can be described as a characteristic of something that distinguishes it from other similar things, such as being different in color, texture, size, shape, sound, smell, taste, or mood. Variability is often associated with diversity and richness, and it can also indicate differences in quality, reliability, or consistency.
