should I use an anova?


New Member
I have numbers of individuals in 3 groups (p, i and g) over 14 different tide heights. These tide heights have been grouped into Low, Mid and High-water.

I want to find out if there is a difference in the proportions of each group between tide heights. I've used an ANOVA single factor, but that doesn't look right.

Hope someone can help,

Thanks, Jude

This sounds like a problem for a chi-squared test.

Check our Examples forum and you'll find an example chi-squared problem.
