Description

Income and job satisfaction by gender.

Usage

jobsatisfaction

Format

A contingency table with 104 observations on 3 variables.

Income

a factor with levels "<5000", "5000-15000", "15000-25000" and ">25000".

Job.Satisfaction

a factor with levels "Very Dissatisfied", "A Little Satisfied", "Moderately Satisfied" and "Very Satisfied".

a factor with levels "Female" and "Male".

Details

This data set was given in Agresti (2002, p. 288, Tab. 7.8). Winell and Lindbäck (2018) used the data to demonstrate a score-independent test for ordered categorical data.
