 Posted - 04/21/2008 :  05:43:02 Hi all,I know there are a few solutions for this out there but non of them suit me. This is my problem.Att1, Att2, Price per unit1, 1, \$0.21, 1, \$0.31, 1, \$0.31, 1, \$0.41, 1, \$0.51, 2, \$0.31, 2, \$0.31, 2, \$0.31, 2, \$0.4This is the table I have and the Att1 and Att2 is to distinguish the product difference. From example above, Att1 = 1 and Att1 = 1 is product A and Att1 = 1 and Att2 = 2 is product B. So, now, how do I find the median price for each product? It doesn't need to be financial median. I have tried a few solutions but they didn't work properly.
