A retail chain keeps daily data with summaries of the dollar amounts of sales for each of 151 different products sold at 23 retail stores. The daily data is tracked by product and by store. At the end of the day each store sends its data to the sales manager at the corporate office. The data is sent in an Excel spreadsheet. Describe a data consolidation strategy and at least two different types of visualization techniques the sales manager can use to analyze the data received from all stores. Be sure to include formulas that are to be used in the Excel spreadsheet.
