Common Question Types
The most common question types used in the multiple choice section were:
- Multiple choice with one correct answer
- Multiple choice with multiple correct answers
- True/False questions
- Fill-in-the-blank questions
To approach these question types, students should:
- Read the question carefully and identify the key concepts.
- Consider all the answer choices before making a selection.
- Eliminate any answer choices that are clearly incorrect.

Data Analysis and Interpretation
Data analysis and interpretation are essential skills in AP Statistics. Students should be able to:
- Summarize and represent data using graphical and numerical methods.
- Identify patterns and trends in data.
- Make inferences about a population based on sample data.
Multiple choice questions on data analysis and interpretation often require students to:
- Interpret graphs and tables.
- Calculate summary statistics.
- Make predictions based on data.
Statistical Inference
Statistical inference is the process of making generalizations about a population based on sample data. Students should be able to:
- Conduct hypothesis tests.
- Calculate confidence intervals.
- Interpret the results of statistical tests.
Multiple choice questions on statistical inference often require students to:
- Identify the appropriate statistical test to use.
- Conduct the test and interpret the results.
- Make conclusions about the population based on the sample data.
Probability and Distributions
Probability and distributions are fundamental concepts in AP Statistics. Students should be able to:
- Calculate probabilities.
- Identify and describe different types of probability distributions.
- Use probability distributions to make predictions.
Multiple choice questions on probability and distributions often require students to:
- Calculate probabilities using different methods.
- Identify the appropriate probability distribution to use.
- Use probability distributions to solve problems.
Regression Analysis
Regression analysis is a statistical method used to investigate the relationship between two or more variables. Students should be able to:
- Identify the appropriate regression model to use.
- Fit a regression model to data.
- Interpret the results of a regression analysis.
Multiple choice questions on regression analysis often require students to:
- Identify the independent and dependent variables.
- Fit a regression model to data using a calculator or software.
- Interpret the slope and intercept of a regression line.
