Four archeological sites (A, B, C and D) are being analyzed. There is an artifact type in

common among all sites. Ten values of artifact length are taken at random in each site. Is

artifact length different among zones?

1. What analysis do you run to answer this question?
2. What graphs do you use to visually compare the magnitude of variability among sites to variances within each site? Illustrate with an example.
3. What is the statistic?
4. What is H0?
5. Suppose you get statistic = 5.8, p-value=0.007. What is your conclusion?
