    Interpreting epsilon squared effect size values

    I've calculated the Kruskal-Willis test to find differences in water accessibility within archaeological groups and have statistically significant results. How do I interpret the epsilon squared values? I understand the range is 0-1, 0 being no difference and 1 being totally different. How...

    one numerical and three categorical variables - which test?

    Thanks for your replies. @Karabiner - As you wrote, each water source may have one or more site connected to it. There are 556 sites (though I might decide to divide this number into several smaller groups later), and there are 194 water sources that are divided into three categories (55, 58...

    one numerical and three categorical variables - which test?

    I am looking at the relation between the distance from archaeological sites to their nearest water source. I have three types of water sources (the categorical data) and a list of many sites, each with a numerical distance value to the closest water sources. I want to know if there's a...

    Which test should I use?

    Hi, Gianmarco I am working with GIS, and do have the geometry. your suggestion sounds like exactly what I need. the polygons do cover the entire study area, but the environmental zones I'm using (the areas) aren't continuous but patchy (i.e. there are two or more non-neighbouring areas that are...

    Which test should I use?

    Hi, Thanks for your reply, I have 437 sites. For now, I want to look at them together but later I might also decide to subdivide them into smaller groups (three, or seven). This is based on archaeological data such as chronology and typology (tool types). There are five area types, which were...

    Which test should I use?

    Hello all, I am a novice in statistics so I hope I explain my question so that you understand, here goes. I have a dataset of archaeological sites that are distributed over a large area. I divided this area into regions according to vegetation characteristics. I've summarized the sites'...
