The adjusted coefficient of determination is calculated using the formula: Adjusted R² = 1 - [(1-R²)(n-1)/(n-k-1)], where R² = 1 - (SSE/SST), n is the number of observations, and k is the number of independent variables. Here, R² = 1 - (0.0625/0.475) = 0.8684. Adjusted R² = 1 - [(1-0.8684)(25-1)/(25-2-1)] = 0.8565.
