Identify the statistical procedures that are appropriate for the data. Childhood participation in sports, cultural groups, and youth groups appears to be related to improved self-esteem for adolescents (McGee, Williams, Howden-Chapman, Martin & Kawachi, 2006) in a representative study, a researcher compares scores on a standardized self-esteem questionnaire for a sample of n = 100 adolescents with a history of group participation and a separate sample of n = 100 who have no history of group participation.
Suppose you do a small-scale study to find out whether relationship satisfaction is related to relationship status (dating, engaged, or married). You take a random sample of 39 participants, 13 of whom belong to each of the relationship status groups. You ask each participant to rate their level of satisfaction with their relationship on a 1 to 10 scale. You wish to conduct a One-Way ANOVA to test whether the differences between the groups are significant. Initial calculations reveal that the Total Sum of Squares is equal to 136.359, and the Sum of Squares for Treatments is 66.513. Find the value of the F-statistic.
