WebbIn other words, the residual standard deviation indicates the accuracy for a model to predict scores, thus it can be thought of as “a measure of the average distance each observation falls from its prediction from the model” ( Gelman, Hill & Vehtari 2024, p.168 ). σ can be considered as a measure of the unexplained variation in the data, or of … WebbStudents will not be expected to calculate s by hand on the AP® Exam.
