ClassTools for AP Statistics: Topic Outline

AP Statistics gives students hands-on experience collecting, analyzing, graphing, and interpreting real-world data. They'll learn to effectively design and analyze research studies by reviewing and evaluating real research examples taken from daily life. The next time they hear the results from another poll or study, they'll know whether the results are valid. As the art of drawing conclusions from imperfect data and the science of real world uncertainties, statistics plays an important role in many fields. AP Statistics prepares students for the AP Exam. The content aligns to the scope and sequence specified by the College Board and to widely used textbooks.
