Common Uses To determine what percentage of Total Sales was contributed to by Incremental Sales with a particular merchandising condition. Usage Notes These measures are not reported for the causal condition “No Merch.” Algorithm % Increase by Merch Measures % Increase in Dollars by Merch m2_325 % Increase in Units by Merch m2_326 % Increase in Volume by Merch m2_327 Definition These measures express the percentage by which sales increase in a week during which a specified merchandising condition occurs. Calculation These measures are calculated as follows: (Sales – Baseline Sales) * 100 Baseline Sales For Units and Volume, if the calculation result is negative, 0 is reported. Baseline Sales are IRI’s estimate of sales in the absence of promotion. Baseline Sales are calculated using IRI’s proprietary baselining algorithm. Common Uses To determine what types of merchandising are most effective. To measure the response to the same types of merchandising across different products and time periods. Usage Notes % Increase in Dollars can be negative. These measures cannot be summed across causal conditions.
