Note that a one- way ANOVA indicates only if a set of differences is statistically significant. For instance, if an ANOVA indicates that the set of mean differences among Groups A, B, and C is significant, it does not indicate which of the following pairs are significant: (1) A versus B, (2) A versus C, and (3) B versus C. In other words, the significant ANOVA indicates only that one or more of these pairs is significant. To pinpoint which pairs(s) are significant, post hoc tests (also known as multiple- comparisons tests) are used. There are several post hoc tests, one of which, known as Duncan's test, is reported below. Note that post hoc tests are run only to compare pairs of means in a set that has first been identified as statistically significant with an ANOVA. Background Notes A one-way ANOVA was run for each row in the table in the excerpt. For each, a value of F is shown. Duncan's test was also run for each row. In a given row, entries with superscript ( ) have significantly different means from entries with superscript ("). Note that as a general rule if there is no indication that a difference (or a set of differences) is significant, the reader should assume that it is not significant. Excerpt from the Research Article As part of a larger study of family functioning, a total of 104 families (adolescents, mothers, and fathers) participated in this study. All participating families in the current study included an ado- lescent, the mother, and the father. Adolescents were required to have at least monthly face-to-face contact with their biological mother and their biological father for inclusion.... Participants completed the age-appropriate version of the Harter Self-Perception Profiles, which conceptualize self-esteem as perceived competence in multiple domains. The social accep tance domain assesses participants' perceptions of feeling accepted by peers, feeling popular, and feeling comfortable around others. The physical appearance domain assesses participants' self- perceptions of their attractiveness and their satisfaction with their appearance. The athletic compe- tence domain assesses participants' feelings of their competence in sports and other physical activi ties. The global self-worth subscale assesses participants' feelings about themselves overall (i.e., not tied to any specific domain...). In order to test for the racial/ethnic group differences..., a series of ANOVAs was completed for each informant (adolescents, mothers, and fathers). Significant ANOVAs were followed up by post hoc Duncan's tests.
