A criminal justice researcher is interested in examining whether students attending three different high schools differ in terms of their sense of safety while at school. Sense of school safety is measured on a scale from 0 to 10 with 0 indicating the student never feels safe at school and 10 indicating the student always feels safe at school. The data below are from a random sample of students from each school:

School A School B School C

1 7 6

2 9 3

4 9 5

4 10 5

5 8 2

a) Perform an ANOVA calculation to test the null hypothesis of no difference in sense of safety at school. Use = .05.
