Methods in Behavioral Research

Methods in Behavioral Researchhas achieved its market-leading position with its concise and strategic approach to methodological decision making. Combining helpful pedagogy and rich examples, Cozby's tenth edition again incorporates learning objectives, illustrative graphics, and activities to increase student involvement. Highlights of the new edition include a broader introduction of different research techniques in Chapter 4, extensive revision of the "validity of measurements" section, and updated structural equations models.
