This is sort of vague.  Specifically what are you looking for?

Data mining typically mean looking for relationships in data that are not obvious.

Looks like you are going from a store aspect.

You would expect sales of sunblock to rise and fall with sales of swim suits.  Sales of snow shovels to rise and fall with bags of rock salt/snow melt.

Data mining looks for correlations that are not obvious.

Stores look at this sort of thing all the time:  If we put 'Pepsi' on sale is Toilet Paper sales correlated?


Not sure if you are missing a comma between beer and formula or you are looking for "beer formula".


But what items rise and fall with the sales of diapers?

I'm not understanding what you would like explained?

Is this a school assignment?


There are a lot of links out there on the beer/diaper debate:
