Implications on the suitability of data analysis methods for the formulation of nutrition policy-relevant questions
The wording of the questions may directly imply a particular data analysis method. For example, a question starting with: “What is the cost-effectiveness of intervention X on…?” directly implies a cost-effectiveness analysis. Therefore, the fact that such a method does not lend itself to analysing existing data has a very direct implication for the feasibility of answering this question.
In some cases, the wording of the question needs to be adjusted so that it implies a data analysis method that is more suitable for answering, fully or partially, the concerns of policy makers. In particular, questions implying an impact evaluation methodology need to be unpacked into sub-questions that address elements along the impact pathway. This is described in section 2.
