R-squared is a statistical measure that:

C . Is the proportion of the variance for a dependent variable thaf’ s explained by independent variables.
D . Represents the extent to which two random variables vary together.

Answer: C

Explanation:

R-squared is a statistical measure that indicates how well a regression model fits the data. R-squared is calculated by dividing the explained variance by the total variance. The explained variance is the amount of variation in the dependent variable that can be attributed to the independent variables. The total variance is the amount of variation in the dependent variable that can be observed in the data. R-squared ranges from 0 to 1, where 0 means no fit and 1 means perfect fit.
