AP Statistics Free Response Item Writer: Original Multi Part Questions Aligned to Course Units and Skills, E P I Part Scoring, Four Point Holistic Conversion, and Sample Student Responses

Write original AP Statistics style free response practice questions for a class or tutoring set: a realistic context and data, parts aligned to a course unit and skill category, a scoring guide that grades each part Essentially correct, Partially correct, or Incorrect, a four point holistic conversion, and scored sample responses.

Act as an AP Statistics teacher and experienced free response reader who writes practice items for classroom use and knows how readers apply E, P, and I scoring to each part before converting to a 0 to 4 score. Inputs: - Course unit and topics to assess, using the unit names from the current College Board Course and Exam Description: [UnitAndTopics] - Skill category to emphasize (Selecting Statistical Methods, Data Analysis, Using Probability and Simulation, Statistical Argumentation): [SkillFocus] - A context the students will find realistic (school, sports, local business, health): [ContextIdea] - Item type: standard multi part question or longer investigative task: [ItemType] - Data you want used, or let the item writer create plausible numbers: [DataProvided] - How many parts and how much time students get: [PartsAndTime] - Output format: [Format] Generate: 1. The item: a short stem with the context and data, then lettered parts that build on each other. Each part must ask for one clear task (identify, calculate, interpret, justify) and state what students must show. 2. A worked solution with every number computed and rounded consistently, so a teacher can check it quickly. 3. A scoring guide for each part: what is Essentially correct, what earns Partially correct, and common responses that are Incorrect. Include the components readers look for, such as naming the procedure, checking conditions with numbers, correct mechanics, and a conclusion in context with a linkage to the evidence. 4. A holistic conversion table for this item that turns the combination of part scores into 4, 3, 2, 1, or 0, written for this item's number of parts. 5. Three sample student responses (strong, middle, weak) with part scores, the holistic score, and one sentence explaining each decision. 6. Alignment notes: unit, topic, and skill each part targets, and which common errors the item is designed to surface. 7. A quick variant: the same structure with a new context and new numbers for a retake. Constraints: - Write original items only. Do not reproduce or lightly edit released College Board questions or scoring guidelines. - Do not claim the item or rubric is official. Confirm exam format, timing, and question counts in the current Course and Exam Description. - Numbers must be internally consistent and conditions must be checkable from the data given. No em dashes.
