Hi everyone,
New to Talk Stats, so be nice! I have looked for an answer to my problem on previous posts but have not been able to find anything suitable.
Basically I am comparing the data between three different groups who have all performed a particular type of examination. I have carried out a Kruskal-Wallis test as my data was positively skewed to the right and I have more than two groups to compare.
My results for one of my variables was .001 and for the other it was .00 which I have managed to expand to .000000000002.
These values have thrown me off a little bit so I need some help, I'm presuming I need to reject the null hypothesis as p=<0.05?
And I was then planning on using the Mann-Whitney U test to compare what two groups have a significant difference.
Is this along the right lines? Using SPSS btw.
Thanks all in advance for any help
