Understanding the AP Statistics Exam Structure

The AP Statistics exam is a comprehensive 3-hour test designed to assess your understanding of statistical concepts, data analysis, and inference. The exam is divided into two equally weighted sections, each contributing 50% to your final score.

Section I: Multiple Choice (50% of Score)

The multiple choice section contains 40 questions to be completed in 90 minutes. These questions test your ability to:

• Interpret graphical displays of data distributions
• Calculate and interpret summary statistics
• Understand probability concepts and distributions
• Apply inference procedures for proportions and means
• Analyze experimental design and sampling methods

Section II: Free Response (50% of Score)

The free response section consists of 6 questions completed in 90 minutes:

• Questions 1-5: Short-answer questions worth 4 points each (20 points total)
• Question 6: Investigative task worth 4 points but weighted double in scoring

How Scoring Works

Your raw scores from both sections are converted to a composite score, which is then translated to an AP score of 1-5. The College Board uses a curve that varies slightly each year based on exam difficulty.

AP Statistics Score Cutoffs

The following table shows approximate score cutoffs based on recent exam data. Note that these can vary by 2-5 points each year:

AP Score	Composite Score Range	Approximate Percentage	Qualification Level
5	70-100	70%+	Extremely Well Qualified
4	57-69	57-69%	Well Qualified
3	44-56	44-56%	Qualified
2	33-43	33-43%	Possibly Qualified
1	0-32	0-32%	No Recommendation

How to Calculate Your AP Statistics Score

The calculation process involves several steps:

1. Calculate MC Raw Score: Number correct × 1.25 = MC weighted score (max 50 points)
2. Calculate FRQ Raw Score: (FRQ 1-5 points × 1.875) + (FRQ 6 points × 3.125) = FRQ weighted score (max 50 points)
3. Add Sections: MC weighted + FRQ weighted = Composite score (max 100 points)
4. Convert to AP Score: Use the cutoff ranges to determine your 1-5 score

Example Calculation

Scenario: A student gets 32/40 on MC, 16/20 on FRQ 1-5, and 3/4 on FRQ 6

MC Score: 32 × 1.25 = 40 points

FRQ Score: (16 × 1.875) + (3 × 3.125) = 30 + 9.375 = 39.375 points

Composite: 40 + 39.375 = 79.375 ≈ AP Score of 5

Tips to Improve Your AP Statistics Score

Multiple Choice Strategies

• Know your calculator: Practice TI-83/84 functions for statistical calculations
• Eliminate answers: Use statistical reasoning to rule out impossible options
• Watch for common traps: Correlation vs causation, confounding variables
• Manage time: Aim for about 2 minutes per question

Free Response Strategies

• Show all work: Partial credit is available for correct reasoning
• Use context: Always relate your answer back to the specific scenario
• Name the test/interval: Explicitly state which procedure you're using
• Check conditions: Always verify assumptions before running inference
• Communicate clearly: Write in complete sentences for interpretations

What Score Do You Need?

The score you need depends on your goals:

• Score of 5: Almost all colleges grant credit; highly selective schools may still require it
• Score of 4: Most colleges grant credit or placement
• Score of 3: Many colleges grant credit; check specific policies
• Score of 2: Few colleges grant credit; still demonstrates effort
• Score of 1: No credit, but the experience still builds skills

Research your target colleges' AP credit policies, as they vary significantly. Some competitive STEM programs may require a 5 for credit, while others accept a 3.
