Describe data cleaning and screening procedures for the initial dataset

  • Introduction
    • One paragraph briefly restating the purpose and focus of the study
  • Information biases
    • Describe the potential information biases in your study
    • Discuss how information bias will be handled or minimized in the study
  • Research questions and hypotheses
    • Restate the study’s research questions along with their associated hypotheses
  • Statistical analysis plans
    • Describe data cleaning and screening procedures for the initial dataset
    • Discuss your plans for initial descriptive analyses and any other preliminary statistics that may be appropriate (e.g., bivariate analyses to assess potential confounders, collinearity analyses)
  • For each research question/hypothesis:
    • Identify the statistical test that will be used to test the association
    • Describe which variables will be included in the analysis and why
    • Identify the measures of association, parameter estimates, or other results, and describe how they will be interpreted
    • Include a discussion of additional procedures as appropriate (e.g., Bonferroni corrections, goodness-of-fit tests, tests for interaction)
