The following example is used for questions 41–50: It is often thought that ethnic minorities tend to be more family oriented than European Americans, often even having multiple generations under the same roof. We wanted to empirically test this folk notion using the MUSIC data of college students from 30 universities across the U.S. We used the Streidel and Contreras’ (2003) 18-item familism scale as a measure of family focus. We ran an ANOVA with follow-up pairwise comparisons. Here is the output. Visual Description c.familism@ethnicity Mean Std. Err. [95% Conf.
