Explanation

The term 'heteroscedasticity' refers to the condition where the variance of errors is not constant across observations, violating the assumption of constant variance. 'Heterogeneous' and 'homogeneous' describe different concepts related to uniformity, while 'homoscedasticity' means constant variance, which is the assumption being violated.
