STATISTICAL GUIDE The symbol for the chi-square test value is x². This is helpful to know, as p in the study below the authors report the value for x². Every value for ² has a p-value associated with it. BACKGROUND NOTE In the excerpt below, the .10 probability level is reported in addition to the more traditional .05 and .01 levels. Also, note that chi-square values are given only for comparisons that are statistically significant. The statistics in the excerpt are for Hispanics residing in California. The data was originally collected by the United States Census Bureau, which used a sample of California residents. EXCERPT FROM THE RESEARCH ARTICLE¹ The sampling frame included the following: only heads of house- holds, persons 16 years of age and older who self-identified as Hispanic regardless of race, householders who worked at some point [during the year], and householders who were employed in their own unincorporated business and professional practice.... The final sample consisted of 7,760 Hispanic self-employed persons, 64% (n=4,931) who were self-employed men and 36% (n=2,829) who were self-employed women.
