My friend is interested in to know if there is significant variation among number of individuals (plants) among three kinds of plots. Each kind of plot has 25 independent repetitions.

I was thinking in to compare the CV among the plots but.... some people from the list are suggesting an one-way ANOVA. What do your think ?
