This article reviews a new statistics textbook by Rory Allen. The book teaches the fundamentals of statistics and experimental design at an undergraduate psychology level. The material is taught from a model comparison perspective, which Allen argues to be more intuitive than traditional null hypothesis significance testing (NHST) approaches. A key feature of the book is an elegant and novel geometric formulation of Fisher’s F, the test statistic in analysis of variance (ANOVA). Allen’s contribution should provide a useful reference for psychology students, especially if future editions incorporate a wider range of statistical methods.
