The correlation coefficient between two quantitative variables is 0.8. What does the value of this correlation coefficient indicate about how well the model fits the data? A. No conclusion can be drawn regarding how well the model fits the data. B. The correlation coefficient is not within the correct range. C. The model is not a good fit. D. The model is a good fit.

The model is a good fit with the correlation coefficient between two quantitative variables being 0.8. The correct option is D.

What is the correlation coefficient?

A correlation coefficient is a metric that expresses a correlation, or a statistical link between two variables, in numerical terms.

The correlation Coefficient is a metric used to evaluate the strength of the relationship between 2 variables, the correlation coefficient ranges from - 1 to + 1 with values closer to either ±1 depicting a stronger and better relationship.

A value of 1 means relationship exists and values close to one mean the relationship is good. With a correlation Coefficient value of 0.08, this value is very close to 1 and hence shows that the relationship is extremely good. Hence, the model is a good fit.

Hence, the model is a good fit with the correlation coefficient between two quantitative variables being 0.8. The correct option is D.
