      In , , and , the Bureau of Mines examined the potential for lode deposits of platinum-group metals (PGM) in the Goodnews Bay Ultramafic complex, Alaska. The complex consists of the Red Mountain, Suzie Mountain, and Smalls River Ultramafic bodies and displays concentric zoning of rock types similar to complexes in southeast Alaska.   To compare two groups, we described how the t test is used (Drummond & Tom, a,b).To compare more than two groups, we would use a different test, analysis of variance (ANOVA). We start with a premise very similar to the logic of the t test: is it possible that these groups could have been sampled from a single population? A variety of forms of analysis of variance exist, Cited by:
