Each chapter contains 30 multiple choice questions and 4 problems (20% increase in multiple choice questions and 33% increase in problems). 8 'Consider This' articles replaced. Most of these articles are from The Economist, so the content is more in line with economic concepts in the book. One third of the chapters contain 'data based problems'. These are in the problems or study questions sections. There is 'real' data provided and students construct graphs or complete calculations and answer questions based on the data. New to the Study Guide and following the 'study questions', 3 web-based exercises have been created for each chapter. Students are sent to a web site (or occasionally asked to find data/information on the web themselves) and use the data and information there to answer questions. The exercises emphasize up-to-date data and information (for example, the mornings exchange rate, this months' CPI) and 'personalized' information that couldn't be included in the study guide (finding unemployment rates for their city or state, calculating education costs using their school, evaluating environmental quality in their zip code). Web sites limited to those that are well-maintained - often US federal government sites. Instructors may also note that the workbook exercises are race and gender inclusive in the examples used, questions asked, data provided, etc.
