1. A scientist is graphing data points from an experiment and concludes that the data set is linear. Which of these statements BEST explains why they drew this conclusion?

Because the relationship between the dependent and independent variables is linear.
Because the variables are independent of each other.
Because the variables are related exponentially.
Because the residuals are random in magnitude.

2. What does homoscedasticity imply?

All values of the dependent variable have a different variance around the regression line.
All values of the independent variable have the same variance around the regression line.
All values of the dependent variable have the same variance around the regression line.
All values of the independent variable have a different variance around the regression line.
