A regression equation is obtained for a collection of paired data. It is found that the total variation is 20.711 , the explaine
d variation is 18.592 , and the unexplained variation is 2.119 . Find the coefficient of determination.
1 answer:
Answer:
0.898
Step-by-step explanation:
The formula for the Coefficient of determination = ratio of explained variation to Total variation
From the above question, we have the following values
Explained variation = 18.592
Total variation = 20.711
The coefficient of determination = 18.592 : 20.711
= 18.592/20.711
= 0.8976872194
Approximately ≈ 0.898
Therefore, the coefficient of determination is 0.898
