Created through a "student-tested, faculty-approved" review process with nearly 100 students and faculty, BSTAT is an engaging and accessible solution to accommodate the diverse lifestyles of today's learners. Written by leading statistics expert and best-selling statistics author Gerald Keller, BSTAT emphasizes applications rather than calculations while vividly demonstrating the vital role of statistics for today's business managers. Readers learn the author's hallmark, three-step approach to using statistical tools to solve actual business problems as they learn to identify the correct technique, compute the statistics, and interpret the results within the correct context.
