Variação is a term that can refer to several concepts, most commonly in the fields of statistics and biology. In statistics, variation refers to the extent to which data points in a dataset differ from each other and from the average value. This is a fundamental concept in understanding the spread and distribution of data. Measures like variance and standard deviation quantify this variability. High variation indicates that data points are spread out, while low variation suggests they are clustered closely together. Understanding variation is crucial for making inferences, testing hypotheses, and building predictive models.

In biology, variation refers to the differences that exist among individuals of the same species. This variation can be seen in physical traits, behaviors, or even physiological processes. Genetic variation, arising from mutations and recombination, is the raw material for evolution. Differences in genes lead to differences in observable characteristics, known as phenotypic variation. Environmental factors can also contribute to variation by influencing how genes are expressed. This biological variation is essential for adaptation and the long-term survival of a species in changing environments. Without variation, populations would be unable to adapt to new challenges or diseases.
