Definitions:

Constant Variance

The condition in which the variance of error terms in a regression model is the same across all levels of the independent variables.

Error Variable

A variable in statistical or mathematical models that represents the difference between observed and predicted values, often due to randomness or unexplained variation.

Outliers

Outliers are data points that deviate significantly from the rest of the data, potentially indicating variability in the measurement or experimental errors.

Regression Line

A straight line that best fits the data points on a scatter plot, showing the relationship between two variables.
