About this resource
This quiz covers sampling methods and experimental design, which are fundamental topics in AP Statistics typically taught to high school students in grades 11-12. The questions assess students' understanding of different sampling techniques including simple random sampling (SRS), stratified sampling, and census methods, as well as their ability to distinguish between observational studies and controlled experiments. Students need a solid foundation in statistical terminology and must understand the principles of randomization, control groups, and confounding variables. The content requires analytical thinking to evaluate study designs, recognize bias and sampling error, and identify the key components that make experiments valid and reliable. Students must also understand concepts like blocking, replication, and the trade-offs between different data collection methods. This quiz was created by a classroom teacher who designed it for students studying AP Statistics in grades 11-12. The assessment serves as an excellent review tool for Unit 3 concepts and can be effectively used as a formative assessment to gauge student understanding before a unit test, as a homework assignment to reinforce classroom learning, or as a warm-up activity to activate prior knowledge before diving into more complex statistical inference topics. Teachers can use this quiz to identify areas where students need additional support in distinguishing between study types and understanding experimental design principles. The questions align with Common Core Standards S-IC.3 and S-IC.6, which focus on evaluating reports based on data and understanding the purposes and differences of sample surveys, experiments, and observational studies.
