There is a comparison and contrast between a purpose statement and a research question. Essentially, the purpose statement comes out of a research question. This lays out the problem and also the purpose of the statement. The purpose statement on the other hand outlines what the researcher would like to cover in order to study the problem. For instance, if one wants to study the negative campaign ads during elections, the research question talks about the number of negative campaign ads. Then after the research question, the purpose of the research follows. The purpose statement highlights the reasons why one would like to perform the study (Söderlund, 2003).
In the research that is to be conducted supposing the research topic is the role of public relation in the environment; dangers and opportunity. The topic statement act like the purpose statement and the research question that can be associated to this is how effective is the role of environmental relation specialist? (Environmental science 2016). The research question and the purpose statement are both tackling the same topic in any research work. In this research the purpose statement is the main guideline on the topics that are to be studied. The research question shows the specific part that the research is to major.
