Comparative and Evaluative Survey:
Comparative Survey: Let us suppose, you wish to compare the "perceived needs of rural and urban women in order to find similarities and dissimilarities, this type of survey is called as comparative survey. 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. In this case also researcher needs pre-existing criteria against which the existing condition is evaluated. The method is called an evaluative survey. Where can this method be applied?
- Evaluate when a new method is started.
- Find out whether the method, which is in operation, is appropriate to meet the criteria selected for the purpose.
