In this new study, all study participants see the original Filtered Picture posted by Katie. They then see one of the following three follow-up pictures
In this new study, all study participants see the original Filtered Picture posted by Katie. They then see one of the following three follow-up pictures posted by Sarah: A. Filtered Picture: Sarah reposts Katie's original picture, so participants see Picture A twice B. Unfiltered Picture: Sarah posts a new, unfiltered picture of Katie (Picture B) C. Neutral Picture: Sarah posts an unrelated picture (An older male bodybuilder - Picture C) Picture A Picture B Picture CParticipants then rate their impressions of Katie's insecurity. The specific question they answer is, "How insecure is Katie?" on a 7-point scale (1 = Not at all insecure; 7 = Very insecure). The authors predict that participants will find Katie more insecure if Sarah posts the new "Unfiltered Picture" of Katie (which Katie probably would have posted herself if she wasn't so insecure) than if Sarah reposts either the original "Filtered Picture" or posts the new unrelated "Neutral Picture". The authors do not expect any differences between the Filtered and Neutral Picture conditions, since neither provide a different version of Katie.

IMPORTANT: The answer options in Canvas may not be in the same order you see them below, so make sure to copy over the CONTENT of the answer and not simply the answer letter (A, B, C, D, or E). Note: If you want to run these analyses yourself, look for the SPSS file called "#3 ANOVA Crash Course Data Filter Spring" in Canvas - not required, but definitely recommended!) 1). What is the independent variable in this study? A. Condition: Original Filtered Picture vs. Unfiltered Picture vs. Neutral Picture B. Condition: Original Filtered Picture vs. Neutral Picture C. Ratings of "How insecure is Katie?" on a 1 (Very insecure) to 7 (Very secure) scale. D. Ratings of "How insecure is Katie?" on a 1 (Not at all insecure) to 7 (Very insecure) scale. E. There is too little information in this study to determine the independent variable.2). What is the dependent variable in this study? A. Condition: Original Filtered Picture vs. Unfiltered Picture vs. Neutral Picture B. Condition: Original Filtered Picture vs. Neutral Picture C. Ratings of "How insecure is Katie?" on a 1 (Very insecure) to 7 (Very secure) scale. D. Ratings of "How insecure is Katie?" on a 1 (Not at all insecure) to 7 (Very insecure) scale. E. There is too little information in this study to determine the dependent variable. You run a One Way AVOVA on this data set and get the following SPSS output.

Note that this one is tricky - some answer options differ in only a single number or word! Pay close attention to details here. A. We ran a One-Way ANOVA with picture condition (Filtered vs. Unfiltered vs. Neutral) as our independent variable and participant ratings of "How insecure is Katie?" as our dependent variable. The One Way ANOVA was not significant, F(2, 89) = 4.22, p = . 18. Participant ratings of Katie's insecurity did not differ between the Unfiltered Picture condition (M = 4.63, SD = 1.38), the Filtered Picture condition (M = 3.90, SD = 1.16), and the Neutral Picture condition (M = 3.83, SD = 0.99). B. We ran a One-Way ANOVA with picture condition (Filtered vs. Unfiltered vs. Neutral) as our independent variable and participant ratings of "How insecure is Katie?" as our dependent variable. The One Way ANOVA was not significant, F(2, 87) = 4.22, p = .18. Participant ratings of Katie's insecurity did not differ between the Unfiltered Picture condition (M = 4.63, SD = 1.38), the Filtered Picture condition (M = 3.90, SD = 1.16), and the Neutral Picture condition (M = 3.83, SD = 0.99). C. We ran a One-Way ANOVA with picture condition (Filtered vs. Unfiltered vs. Neutral) as our independent variable and participant ratings of "How insecure is Katie?" as our dependent variable. The One Way ANOVA was significant, F(2, 87) = 4.22, p = .018. Tukey post hoc tests showed that participants felt Katie was more insecure in the Unfiltered Picture condition (M = 4.63, SD = 1.38) than in both the Filtered Picture condition (M = 3.90, SD = 1.16) and the Neutral Picture condition (M = 3.83, SD = 0.99).C. We ran a One-Way ANOVA with picture condition (Filtered vs. Unfiltered vs. Neutral) as our independent variable and participant ratings of "How insecure is Katie?" as our dependent variable. The One Way ANOVA was significant, F(2, 87) = 4.22, p = .018. Tukey post hoc tests showed that participants felt Katie was more insecure in the Unfiltered Picture condition (M = 4.63, SD = 1.38) than in both the Filtered Picture condition (M = 3.90, SD = 1.16) and the Neutral Picture condition (M = 3.83, SD = 0.99). Participants also thought Katie was more insecure in the Filtered Picture condition than in the Neutral picture condition. D. We ran a One-Way ANOVA with picture condition (Filtered vs. Unfiltered vs. Neutral) as our independent variable and participant ratings of "How insecure is Katie?" as our dependent variable. The One Way ANOVA was significant, F(2, 87) = 4.22, p = .018. Tukey post hoc tests showed that participants felt Katie was more insecure in the Unfiltered Picture condition (M = 4.63, SD = 1.38) than in both the Filtered Picture condition (M = 3.90, SD = 1.16) and the Neutral Picture condition (M = 3.83, SD = 0.99). Ratings did not differ between the Filtered and Neutral Picture conditions. E. We ran a One-Way ANOVA with picture condition (Filtered vs. Unfiltered vs. Neutral) as our independent variable and participant ratings of "How insecure is Katie?" as our dependent variable. The One Way ANOVA was significant, F(2, 89) = 4.22, p = .018. Tukey post hoc tests showed that participants felt Katie was more insecure in the Unfiltered Picture condition (M = 4.63, SD = 1.38) than in both the Filtered Picture condition (M = 3.90, SD = 1.16) and the Neutral Picture condition (M = 3.83, SD = 0.99). Ratings did not differ between the Filtered and Neutral Picture conditions
