What to do when the data doesn’t fit the analytical question?

Shrewd reaction to this inquiry can be – well, it is possible that we get the new information, or new question! 

How about we envision our assignment is to discover similitude between individuals from the same gathering, for instance – home advance clients. Presently, envision the circumstance where we ONLY have an information for the home advances clients. 

We can unquestionably look at all their qualities, yet there is no certification that they will be unique in relation to buys of some other saving money items. What we need is some perspective. We require extra information of clients who have whatever other item other than home credits. In this way, keeping in mind the end goal to discover what is something comparative about them, we have to figure what is distinctive amongst them and any other person – which is essentially one and a same thing. 

This is constantly order issue which we attempt to understand by unary target variable (where all buyers having the same estimation of the item acquired). In this way, since we don't have, or can get - extra information for clients that have different sorts of items – we have to go for second-best situation. In this way, rather than "reformulating" information through the sly and inventive information readiness to better fit expository inquiry – we have no other alternative yet to do precisely inverse – reformulating investigative inquiry to fit the current information. 

This would imply that our new question ought to be what are the gatherings of closeness inside the single class of advance clients, and how would they contrast from different gatherings of credit clients – as restrict to the first question of what makes my "advance" clients comparable? This is presently altogether different inquiry and by reformulating our inquiry we are additionally picking new "device" from our workbench, so as opposed to utilizing some arrangement calculation we are returning to grouping technique. 

Thus, the typical reason where information and logical techniques are elements of business inquiry – doesn't work in this circumstance, so down to earth arrangement is to modify the underlying goal.
