The grading rubric for each free-response question is: 4: Complete Response: Shows complete understanding of the problem's statistical components 3: Substantial Response: May include arithmetic errors, but answers are still reasonable and show substantial understanding of the problem's statistical components 2: Developing Response: May include errors that result in some unreasonable answers, but shows some understanding of the problem's statistical components 1: Minimal Response: Misuses or fails to use appropriate statistical techniques and shows only a limited understanding of statistical components by failing to identify important components 0: No Response: Shows little or no understanding of statistical components What does holistic grading mean for you?
