定义为一组特定的方法论原则，提供了一套特定的模块化的假设进行研究所需要的理论解释。佩恩和派恩（2004）进一步补充，方法是用来表示一个集合的概念和哲学假设，证明一个特别的使用方法。它也可以被定义为一种方法，用于辅助数据的收集和分析的规则系统（Hart，1998）。从上面的定义，可以推断，方法提供了重要的理论分析的基础上，特别是研究的特定主题的理论和假设。
本研究的理论视角是后实证主义的立场如下：
本体：这个以批判现实主义的观点；指出，尽管现实是存在的，它不能被充分探讨既然是自然规律，只能部分理解的控制下（Guba，1990）。从研究问题上，某些因素是负责小儿麻痹症在尼日利亚流行，而一些是加强免疫接种。因此，本研究的研究旨在充分探索这些因素。
认识论：客观性仍然是一个控制模型，但这只能通过将更重视外部因素如决定性的社区和批判传统估计（Guba，1990）。客观的立场是保持整个研究和本站有助于消除偏差以保证严谨性和公信力。
本研究的方法是一个文献综述。文献综述已被选定，以探索各种因素促进或阻碍了成功的免疫对消除小儿麻痹症从尼日利亚在更广泛的角度从以前的研究。文献综述，使容易收集的数据从一个广泛的来源和作者对主题的不同观点的理解，从而确定了进一步的研究的差距。

O' Leary, (2004) defines methodology as a particular set of principles that provides theoretical explanation to a particular set of modular assumptions needed in conducting a research study. Payne and Payne, (2004) further added that methodology is used to indicate a set of conceptual and philosophical assumptions that justify the use of a particular method. It can also be defined as a system of methods and rules which are used to aid the collection and analysis of data (Hart, 1998). From the above definitions, it can be deduced that methodology provides the basis for critical analysis of the theories and assumptions on the particular topic being researched.
The theoretical perspective of this research is post positivism and the stances are as follows:
Ontology: This takes the view of the critical realist; stating that even though the reality is out there, it can never be fully explored since it is under the control of natural laws that can only be partially understood (Guba, 1990). From the research question, certain factors are responsible for polio being endemic in Nigeria while some are enhancing its eradication by immunization. Therefore, this research study seeks to fully explore these factors.
Epistemology: Objectivity remains a controlling model but this can only be estimated by attributing more importance to external factors such as decisive community and critical tradition (Guba, 1990). An objective stand is maintained throughout this research study and this stand helps to eliminate bias so as to ensure rigour and credibility.
The methodology for this research is a literature review. Literature review has been selected in order to explore the various factors enhancing or hindering the success of immunization towards eradicating polio from Nigeria in a broader perspective from previous studies. The literature review enables easy collection of data from a wide range of sources and the understanding of different views of authors on the topic thereby identifying gaps for further research.
