Homoscedasticity means that the variance of the errors is consistent across all levels of the independent variable. This is important because if the variance of the errors changes, it can bias the estimates of the regression coefficients and make the results unreliable. Therefore, homoscedasticity is a necessary assumption for many statistical tests, such as t-tests and ANOVA, and for accurate confidence interval and prediction interval calculations.
