Example 157.5 A study reported in 2010 in the Journal "Archive of Sexual Behavior" looked at Sexual practices in healthy Euro-American, Asian, and Hispanic female populations. A portion of the research looked at the age of sexual debut (the age that women first engaged in intercourse)for women in the three study populations. An ANOVA CRD was conducted using SPSS to determine if there was a difference in the age of sexual debut among the three groups of women. The results are reported below. Based on the results below, does there appear to be a significant difference between the groups of women? Based on the results of the ANOVA procedure below, what (if any) multiple comparison procedure should be conducted on the data?
