Riassunto

Written for students taking their first course in psychological statistics, Vernoy and Kyle’s text is considered by many to be the most student-oriented text on the market. Besides a clear and friendly style, the authors avoid digressions of any type, get to the point quickly, provide an abundance of worked examples, visual displays, interim concept quizzes, and other means of reassuring students uncomfortable with math that they are indeed making progress in the course.
