Some people believe in the ability of an astrological, or zodiac, sign (e.g, Scorpio, Sagittarius, Leo, etc.) to influence the course of their lives. A human resources director was interested in examining what, if any, relationship there is between a person’s astrological sign (ASTRO) and a person’s degree of satisfaction with his or her job (SATJOB), measured on a scale from “strongly dissatisfied” to “strong satisfied.” ASTRO and SATJOB are two categorical variables. What type of hypothesis test could be performed to address this question?

a two-sample test for proportions

a two-sample t-test for means

chi-squared goodness-of-fit test

chi squared test of independence

Solution

chi squared test of independence
