How many categories should jane use to track multiple levels of information learned through a student survey on teachers at her school?

The correct answer is C) as many categories as she needs to understand the result.  

The number of categories that Jani should use to track multiple levels of information learned through a student survey on teachers at her school is as many categories as she needs to understand the result.  

Jani needs to sort out the kind of information resulted from the student’s survey on teachers. She has to be smart enough to contemplate all the possibilities so she has to consider as many categories as she needs to understand the result. If she also uses information tools to better understand the result such as charts or graphic organizers, it is going to be easier for her to understand the result.  

The other options of the question were a) one category per teacher, b) one teacher per category, and d) none of these.
