ap statistics - q&a: chi-square, bayes & transformations
originally streamed in 2020 with Bob AmarTeachercurriculum note
This video was recorded during COVID-era AP exam modifications when the instructor states that chi-square tests and data transformations had been removed from that year's exam, and mentions there will be no MCQ. These topics ARE fully tested on the current AP Statistics exam, and the standard exam format (with MCQ) has been restored.
