Question

The assumption of homoscedasticity is that _________. the range of the Y scores is the same as the X scores the X and Y distributions have the same mean values the variability of Y doesn't change over the X scores the variability of the X and Y distributions is the same

Answer 1

Answer:

The assumption of homoscedasticity is that "the variability of Y doesn't change over the X scores."

Step-by-step explanation:

The assumptions of linear regression are:

• Linear relationship
• Multivariate normality
• Almost 0 mulitcollinearity
• 0 Autocorrelation
• Homoscedasticity

The assumption of homoscedasticity implies that the variance of the dependent variable Y, across the regression line does not changes for all values of the predictor variable X.

Thus, the complete statement is:

The assumption of homoscedasticity is that "the variability of Y doesn't change over the X scores."
