Business and marketing professionals have to answer tough questions. "How much do 20-to-29-year-olds in New York spend in restaurants?" "What's the potential market for a $1,200 stereo system?" "Where can I find customers for a home manicure service?" Statistics can be intimidating. How do you use data to determine the direction of your group or product? What are nominal and ordinal variables anyway? In The Complete Idiot's Guide® to Business Statistics, Dr. Sunny Baker gives readers a step-by-step guide to choosing, using, and interpreting statistical analyses for business. The author approaches statistical evaluations as concepts, focusing on the data business people need to interpret and put together, and not on the arithmetic, symbols, and calculations alone. Covering tendency, variables and distributions, this title shows how to use this data for business including sampling, generalizations, analyzing data, and correlation theories. Using real business scenarios as example, The Complete Idiot's Guide® to Business Statistics becomes a handbook for real-life business and marketing professionals.
