In the analysis of comparative survey data, a-pre-existing criteria should be there. In this example the researcher requires a list of needed criteria against which the comparison would be made between the urban and rural women's perception of nutritional needs.
Evaluative Survey: There is another type of survey approach appropriate for studying the effectiveness of a particular method: this is where the researcher attempts to asses whether or not the method used meets the criteria stated.
