Table 0 (Often in Appendix)

  • Variable names and description

  • Saves editors and reviewers’ time by advising them of what variables represent.

Table 1

The first table in the manuscript

  • Empirics start with Table 1.

  • After the abstract, Table 1 is the most critical part of the paper.

  • The first and most important table in the manuscript

  • Sets the stage for the evidence that follows

  • Should present sufficient evidence to necessitate the need for further inquiry

  • Must present only relevant variables and appropriate summary statistics

    • Means and Standard Deviations for continuous variables

    • Frequencies and percentages for categorical variables

  • Show tests if necessary
