What is heteroskedasticity?

Heteroscedasticity is a term used in statistics to describe a non-uniformity in the measure of variation of data. It refers to a situation where the variation in the data in a given data set is not constant, but changes as the standard deviation from the baseline increases. A common example of heteroscedasticity is when the standard deviation of a data set increases as the value of the dependent variable increases.
