SAGE's Quantitative Applications in the Social Sciences (QASS) Series has served countless students, instructors, and researchers in learning cutting-edge quantitative techniques. This collection of 175 brief volumes, the first of which published in 1976, address advanced quantitative topics including Regression, Models, Data Analysis, Structural Equation Modeling, Experimental Design, Factor Analysis, Measurement, ANOVA, Survey Data, and more. A hallmark of the Series has always been its affordability – each book is $22.
