JobSat: Cross-classification of job satisfaction by income

In vcdExtra: 'vcd' Extensions and Additions

Description

This data set is a contingency table of job satisfaction by income for a small sample of black males from the 1996 General Social Survey, as used by Agresti (2002) for an example.

Usage

data(JobSat)

Format

A 4 x 4 contingency table of income by satisfaction, with the following structure:

 table [1:4, 1:4] 1 2 1 0 3 3 6 1 10 10 ...
 - attr(*, "dimnames")=List of 2
  ..$ income      : chr [1:4] "< 15k" "15-25k" "25-40k" "> 40k"
  ..$ satisfaction: chr [1:4] "VeryD" "LittleD" "ModerateS" "VeryS"

Details

Both income and satisfaction are ordinal variables, and are so ordered in the table. Measures of association, visualizations, and models should take ordinality into account.
