D) Regression analysis with R squared of 0.89.

Question

Quizplus · Accepted Answer

R-squared measures the proportion of the variation in the dependent variable that is explained by the independent variable(s) in a regression model. An R-squared value of 0.89 indicates that 89% of the variation in the dependent variable can be explained by the independent variable(s) in the model, making it the most accurate cost estimation method in this scenario. A higher R-squared value means that the regression model fits the data better and provides a more reliable estimate of the cost.
