A researcher explored whether facial symmetry influences perceived attractiveness in potential mates. To do this, he showed participants several headshots of people who had low, moderate, or high facial symmetry and asked them to rate each picture in terms of attractiveness (on a 0-10 scale). Following data collection, the researcher ran a one-way between-subjects ANOVA to test his hypothesis. The Shapiro-Wilk test for normality yielded a Sig. of .083. The mean for low facial symmetry was 8.00 with a standard deviation of .8660. Moderate facial symmetry Mean was 5.00 with a standard deviation of .8165. High facial symmetry had a mean of 7.00 with a standard deviation of .8660. Using the SPSS output below, answer the following questions about this analysis: Is "Attractiveness" normally distributed? Does "Attractiveness" have any outliers? What is the M & SD for each group (low, moderate, & high facial symmetry)? Which group had the highest attractiveness ratings on average? Which group had the lowest attractiveness ratings on average? Like 0
