Hi all,

I need a little advice from your expertise...

I have a pool of data which contains a list of stores and their sales quantity for 4 sizes, namely S, M, L, XL.

ie:

Store Size Quantity

2 S 5483

2 M 6444

2 L 5883

2 XL 3165

7 S 4931

7 M 5963

7 L 4915

7 XL 2469

12 S 115

12 M 149

12 L 94

12 XL 65

For each store, I need to label them to 1 of the 4 size group. Which means, store 2 belong to size group S because they are selling more of the S size, store 7 belongs to size group XL because they are selling more of size XL etc for all stores.

Please note that each store did not receive the same quantity of each size, and hence I didn't not analyze based on their sales quantity but rather their sales % contribution of each size instead... and the % variance of each size compare to the sales % contribution of all stores combined...

(Please find attached excel file for better understanding...)

And I got stuck here...

Can some please give me advice if I am going to the right direction? If yes, how should I proceed further.

Thank you for your help in advance.

Henry.
