Participants are asked to rate their own IQ. Before the estimations one group is told they have just failed a general knowledge test, one group is told they did well and a third group is given no information. Differences between estimates of each group are investigated and data are treated as satisfying parametric assumptions.
-6) An appropriate analysis would be:

A one-way between groups ANOVA is the appropriate analysis because the participants are divided into three distinct groups based on the information they were given, and their IQ estimations are being compared between these groups. The one-way repeated measures ANOVA would be appropriate if the same participants were being measured at multiple time points, and multiple regression would not be appropriate for this type of analysis. Friedman's test is a non-parametric test for ranking data and would not be appropriate for this scenario, as it assumes the data are not normally distributed.
