Well-reasoned research questions or hypotheses lead directly to the variables that need to be analyzed and the methods of analysis. The analysis plan usually begins with the research questions or hypotheses you plan to address.

Tables shells to be included in final report.

Measures of occurrence, association, tests of significance, or confidence intervals to be used.

Order of analysis (e.g., frequency distributions, two-way tables, stratified analysis, dose-response, or group analysis).

How variables will be analyzed (e.g., as a continuous variable or grouped in categories).

Stratification variables (e.g., potential confounders or effect modifiers).

Key variables (attach data dictionary of all variables).

Source of data or data sets, particularly for secondary data analysis or population denominators.

Description of population or groups (inclusion or exclusion criteria).

List of the research questions or hypotheses.

Some of the listed elements are more likely to appear in an analysis plan for a protocol-based planned study, but even an outbreak investigation should include the key components in a more abbreviated analysis plan, or at least in a series of table shells. It lays out the key components of the analysis in a logical sequence and provides a guide to follow during the actual analysis.Īn analysis plan includes some or most of the content listed in Box 8.1. It describes where you are starting (data sources and data sets), how you will look at and analyze the data, and where you need to finish (final report). Therefore, the time to decide what data to collect and how to analyze those data is before you design your questionnaire, not after you have collected the data.Īn analysis plan is a document that guides how you progress from raw data to the final report. Planning is necessary to ensure that the appropriate hypotheses will be considered and that the relevant data will be collected, recorded, managed, analyzed, and interpreted to address those hypotheses. A thoughtfully planned and carefully executed analysis is as crucial for a field investigation as it is for a protocol-based study.
