STATISTICAL GUIDE The title of Table 1 in the excerpt below refers to bivariate correlations-a term often used by researchers. The prefix bi- means two. Hence, bivariate refers to the fact that there are two See Exercise 4.1 for variables involved in each correlation coefficient in the table, A large majority of correlations in review of inverse the research literature are bivariate correlations; so researchers sometimes drop bivariate, and just use the word correlation alone. Still, using bivariate correlation is more precise than just using correlation, Bivariate correlations are often presented in tables like the one below, To read the table, pay attention to the variable numbers, which are in bold. 1 refers to "Community violence exposure. " both in the column going down and the row going across. BACKGROUND NOTE Note that in Table 1 of the excerpt, SAT-9 stands for the Ninth Edition of the Stanford Achievement Test, a standardized test that is widely used nationally. EXCERPT FROM THE RESEARCH ARTICLE Participants were recruited from an elementary school located in an urban section of Los Angeles County . . . The families living in the surrounding neighborhoods have been conceptualized as "working poor" in recent demographic studies of the Los Angeles region. .. All children in 16 third-, fourth-. and fifth-grade classrooms from the participating school were invited to take part in the project. Of these children, 80% returned positive parental permission and assented to participate. Community violence exposure. Children completed the Community Experiences Questionnaire. . . Items on this measure range in severity from threats to shootings, the 4-point scale ranges from 1 (never) to 4 (a lot of times). Bullying by peers. [A second inventory] contained four items assessing bullying by peers ("kids who get hit or pushed by other kids," "kids who get bullied or picked on by other kids." -kids who have mean things said about them by other kids, " and "kids who get left out of fun games or play when other kids are trying to hurt their feelings"). . . .
