Key Questions of Bivariate Tabular Analysis

  1. Is there a relationship between the independent variable and the dependent variable?
    • Changes in the distributions of the dependent variable across the categories of the independent variable (i.e. the column percentages change across the rows)

  2. How strong is the relationship?
    • Magnitude of the differences in the percentages across the rows
    • Magnitude of the measures of association

  3. What direction is the relationship? (ordinal level variables only)

  4. If your data are from a sample, can we conclude that the relationship we find the in the table is the product of a real relationship in the population from which the sample was drawn (ie. can we reject the null hypothesis for the population)?

  5. Are there other variables that could account for the relationship you have found?
