The proportion of variation explained by the independent variables in the regression can be calculated using the formula R-squared = 1 - SSE/SST. Applying this formula yields R-squared = 1 - 82.04/102.55 = 0.199, or 19.9%. Therefore, it can be said that only 19.9% of the variation in the dependent variable is explained by the independent variables in the regression, not 90%.
