Questions and answers on this set of more than 450 flash cards encompass four general statistics-based themes: exploratory analysis, planning a study, probability, and statistical inference. New to this edition are 50 extra multiple-choice questions that cover all topics. The cards measure 4 1/2" x 2 3/4" and have a punch-hole in one corner that accommodates an enclosed metal key-ring-style card holder. The ring allows students to arrange the flash cards in any sequence that suits their study needs. A valuable study aid, whether used alone or in tandem with Barron's AP Statistics review book. BONUS! An exclusive online exam included with the purchase of the flash cards.
