I've just finished my undergrad thesis and the reviewers strongly recommended that I pursue formal publication of my results. I thought 'COOL'.

However, I've just realised that my stats were a bit off and as such I'm redoing everything. I have Likert scale data (1-7) an n of 300 so from reading it appears that the Kruskal-Wallis test is the best. However I'm having issues understanding the results of the test. As the Uni-umbilical chord has been cut, I need to look to lovely folks such as yourselves for help and advise

Can anyone help with the following questions, please!

- How do I know if my data is tied?

I can't tell exactly, but as I understand it, if two (or more) groups reports the same median response to a scale, they are tied? (eg. two medians of 7)

- What does my p-value truly signify?

As I understand, a low p (at alpha 0.05) signifies that there is a detectable difference between some of the groups.

- Do the results of the Dunn test give me a pretty good idea of where my main diferences lie?

As I understand, the Dunn test will tell me which groups have the*greatest*detectable difference?

Any help, advice, thoughts or questions would be much appreciated.:tup:
