The value of the coefficient of determination is gives the percentage of the variation which is explained by the regression line. The value of the coefficient of determination is the R² value which is 68%.

  • The Coefficient of determination is the proportion of change in the regression model caused by the regression line.

  • From the computer output, the coefficient of determination is denoted as R² ; which is given as 0.68

  • Expressing the value as a percentage ; 0.68 × 100% = 68%

Therefore, the coefficient of determination is 0.68
