Q. 13
Question
13. Identify a use of the coefficient of determination as a descriptive measure.
Step-by-Step Solution
Verified Answer
The regression equation is used to make predictions on the basis of this measure.
1Step 1: Concept Introduction
A coefficient of determination is an indicator of how useful a regression equation is for creating predictions.
2Step 2: Explanation
As a measure of the goodness of fit of a model, the coefficient of determination provides information about the reliability of the model.
A regression line's fit to the actual data is measured in terms of this criterion.
Thus, when a statistical model is used to forecast future outcomes or to test hypotheses, it is imperative to use it correctly.
A goodness-of-fit measure describes how useful the regression equation is for deriving predictions.
