TwoWay is an online app for exploring concepts related to relationships between two categorical variables:

  • Forming an Eikosogram/Mosaic plot of the two-way Table
  • Constructing the counts/frequencies that would be expected  if the variables were independent
  • Comparing the observed and expected counts
  • Morphing from an Eikosogram to a side-by-side barchart representations

Note: Input data has to be in “unit-record” format with one row per individual and columns corresponding to variables
