An example of continuous variation is body size. Continuous variation refers to variation that can take on any value within a range, rather than being limited to certain discrete options. Body size is a good example of this because it can vary continuously from very small to very large, with many possible sizes in between. For instance, a person can be very short, moderately short, of average height, moderately tall, or very tall. This variation is not limited to a certain number of options, and each person's size can be measured and compared to others on a continuous scale.
