Двенадцатое издание пособия "Понятная статистика: концепции и методы" является тщательной, но доступной программой, призванной помочь студентам преодолеть свои опасения по поводу статистики. Авторы дают четкие указания и неформальные советы, показывая студентам связи между статистикой и миром. Чтобы усилить этот подход, книга объединяет реальные данные из различных источников, включая журналы, периодические издания, газеты и интернет. В двенадцатом издании по-прежнему рассматривается важность развития у учащихся навыков критического мышления и статистической грамотности с помощью специальных функций и упражнений по всему тексту. Использование графических калькуляторов, Excel, MINITAB и SPSS предполагается, хотя и не требуется. Обширные технологические ресурсы включают MindTap, онлайн-персонализированную среду обучения, которая сочетает в себе инструменты обучения студентов, такие как чтение, мультимедиа, мероприятия и оценки, в единый путь обучения.
