Attempting to run a bartletts test of homogeneity of variances and I am presented with the following output.
Bartlett test of homogeneity of variances
data: Abundance by Depth
Bartlett's K-squared = 35.697, df = 2, p-value = 1.772e-08
Testing with Shapiro-Wilk test for normality determined that the three levels of the factor Depth are normally distributed. Abundance data has been standardised to 1m2 from a 0.2m2 sample.
Data was loaded into R by selecting a sheet from an excel document in the following format
Any idea what's going wrong? Am I mistaken about the P values?
