Sagot :
The coefficient of determination is 1.
Given
Total Sum of squares (SST) = 90
Sum of squares due to error (SSE) = 0
We have to find coefficient of determination.
The correlation of determination is the ratio of the explained variation to the total variation.
The coefficient of determination is used to analyze how differences in one variable can be explained by a difference in a second variable.
The coefficient of determination is also called r-squared or r-square.
Its the percentage of variation in the y-variable(response) that can be explained by the least squares regression line of y on x.
Coefficient of determination can be found with the following formula:
Formula of coefficient of determination :
[tex]R^{2} = 1 - \frac{SSE}{SST}[/tex]
= 1 - [tex]\frac{0}{90}[/tex]
= 1 - 0
= 1
[tex]R^{2}[/tex] = 1
Therefore,
The coefficient of determination is 1.
