The research proposal should provide information and justification about sample size. It is not necessarily true that the bigger the sample, the better the study. Beyond a certain point, an increase in sample size will not improve the study It is much better to increase the accuracy and richness of data collection. It is better to make extra effort to get a representative sample rather than to get a very large sample. 43

…Sample Size For calculating sample size before the study begins, the researchers have to make a decision on the level of statistical power they are willing to accept for the study. Traditionally, most studies set a power of 80%. 44

Sample size …(for qualitative study) There are no fixed rules for sample size in qualitative research. The size of the sample depends on what you try to find out, and from what different informants or perspectives you try to find that out. You can start with two or four Focus Group Discussions (FGDs) depending on the complexity of the research objectives. If the different data sets reconfirm each other you may stop at this point; otherwise you conduct one or two FGDs more till you reach the point of redundancy , i.e. no new data comes up any more. 45

Analysis Plan Specify the analysis procedures you will use, and label them accurately. The analysis plan should be described in detail. If coding procedures are to be used, describe reasonable detail. If you are triangulating , carefully explain how you are going to do it. Each research question will usually require its own analysis. Thus, the research questions should be addressed one at a time followed by a description of the type of statistical tests (if necessary) that will be performed to answer that research question. 46

…Analysis Plan Be specific. State what variables will be included in the analyses and identify the dependent and independent variables if such a relationship exists. Decision making criteria ( e.g. , the critical alpha level) should also be stated, as well as the computer software that will be used (if there is a need to use one). Statistical software like SPSS, Stata, etc. These help you and the reader evaluate the choices you made and procedures you followed. 47

Work plan Work plan is a schedule, chart or graph that summarizes the different components of a research proposal and how they will be implemented in a coherent way within a specific time-span. Example: GANTT Chart 48

…Work plan It may include: The tasks to be performed; i.e. What is to be performed When and where the tasks will be performed; Who will perform the tasks and the time each person will spend on them; It describes the plan of assessing the ongoing progress toward achieving the research objectives; The plan specifies how each project activity is to be measured in terms of completion, the time line for its completion; A good work time plan enables both the investigators and the advisors to monitor project progress and provide timely feedback for research modification or adjustments.
