Valeria was interested in researching whether different types of exposure to nature would have an impact of a persons level of nature relatedness. She recruited 15 undergraduate participants, and divided them into three groups: control, nature photos and nature walk. The control group simply came to the lab, looked at a series of images of abstract art on a computer for 10 minutes, and then gave ratings on how connected they felt to the natural world on a scale of 1 to 10 (i.e., nature relatedness). The nature photos group came to the lab and looked at different photographs of nature scenes (e.g., lakes, forests, plains) for 10 minutes, and then gave their nature relatedness ratings. The nature walk group met Valeria at a trail near the university that followed along that wound through a nearby Green Belt forested area. At the end of a 10-minute walk, they gave their nature relatedness ratings.

Below is the data from Valerias experiment. Conduct an appropriate ANOVA on the data, state the critical F-value and your decision about the null hypothesis, calculate the effect size, and run the post-hoc comparisons if necessary (calculate Tukeys HSD, calculate mean differences, and make statement about which ones are significant and non-significant). Use the tables provided to calculate your sums of squares and fill out the provided ANOVA tables.
