Hi,
I have a raw data file that has almost 80 columns. My main focus is on columns Question ID, Respondent ID, and Item ID.
Like for eg: ITEM ID "143585" has a corresponding respondent ID and RespondentID has a corresponding question ID. But If I filter on question ID = 91, then ITEM ID is NULL but it has respondent IDs. I want to link all questions ids to item id's as well
Like if I filter on question ID = 91 then it should not give me null values.
Any help is appreciated. Thanks in advance
