A)there is a nonlinear relationship between the X and Y scores.

D)the Y' scores are spread out to the same degree at every X.

Question

Quizplus · Accepted Answer

Homoscedasticity refers to the situation where the variances of the Y scores are equal at every level of X. This means that the spread of the Y scores is consistent across the range of X values, rather than getting wider or narrower as X increases or decreases. Options A and B describe situations where there is heteroscedasticity, or a lack of equal variances across the X range. Option D seems to have a typo and is unclear, but does not describe homoscedasticity.
