You create three versions of a survey, each with different ways of phrasing the questions (positive, negative, or neutral). You randomly assign participants to one of the three surveys, each of which has 20 items for which participants rate their agreement. After collecting the surveys, you calculate an average agreement score for each participant. If testing hypotheses about question phrasing on agreement, it would be most appropriate to calculate a. 1) O One-way (independent) ANOVA ›2)Repeated measures ANOVA 3) factorial ANOVA Factorial ANOVA
