What affects flat panel LCD TV sales? Flat panel LCD televisions are sold through a variety of outlets such as large and small electronics stores, department stores, large discount chains and online. Sales figures (number of units) for the popular Sony Bravia were obtained for last quarter from a sample of 30 different stores. Also collected were data on the selling price and amount spent on advertising the Sony Bravia (as a percentage of total advertising expenditure in the previous quarter) at each store. Below are the multiple regression results. What affects flat panel LCD TV sales?
